// FAQ
//
// Q: What counts as a tilemap for this library?
//
// A: An array of rectangles, where each rectangle contains a small
// stack of images.
//
// Q: What are the limitations?
//
// A: Maps are limited to 4096x4096 in dimension.
// Each map square can only contain a stack of at most 32 images.
// A map can only use up to 32768 distinct image tiles.
//
// Q: How do I compile this?
//
// A: You need to #define several symbols before #including it, but only
// in one file. This will cause all the function definitions to be
// generated in that file. See the "HOW TO COMPILE" section.
//
// Q: What advantages does this have over a standalone editor?
//
// A: For one, you can integrate the editor into your game so you can
// flip between editing and testing without even switching windows.
// For another, you don't need an XML parser to get at the map data.
//
// Q: Can I live-edit my game maps?
//
// A: Not really, the editor keeps its own map representation.
//
// Q: How do I save and load maps?
//
// A: You have to do this yourself. The editor provides serialization
// functions (get & set) for reading and writing the map it holds.
// You can choose whatever format you want to store the map to on
// disk; you just need to provide functions to convert. (For example,
// I actually store the editor's map representation to disk basically
// as-is; then I have a single function that converts from the editor
// map representation to the game representation, which is used both
// to go from editor-to-game and from loaded-map-to-game.)
//
// Q: I want to have tiles change appearance based on what's
// adjacent, or other tile-display/substitution trickiness.
//
// A: You can do this when you convert from the editor's map
// representation to the game representation, but there's
// no way to show this live in the editor.
//
// Q: The editor appears to be put map location (0,0) at the top left?
// I want to use a different coordinate system in my game (e.g. y
// increasing upwards, or origin at the center).
//
// A: You can do this when you convert from the editor's map
// representation to the game representation. (Don't forget to
// translate link coordinates as well!)
//
// Q: The editor appears to put pixel (0,0) at the top left? I want
// to use a different coordinate system in my game.
//
// A: The editor defines an "editor pixel coordinate system" with
// (0,0) at the top left and requires you to display things in
// that coordinate system. You can freely remap those coordinates
// to anything you want on screen.
//
// Q: How do I scale the user interface?
//
// A: Since you do all the rendering, you can scale up all the rendering
// calls that the library makes to you. If you do, (a) you need
// to also scale up the mouse coordinates, and (b) you may want
// to scale the map display back down so that you're only scaling
// the UI and not everything. See the next question.
//
// Q: How do I scale the map display?
//
// A: Use stbte_set_spacing() to change the size that the map is displayed
// at. Note that the "callbacks" to draw tiles are used for both drawing
// the map and drawing the tile palette, so that callback may need to
// draw at two different scales. You should choose the scales to match
// You can tell them apart because the
// tile palette gets NULL for the property pointer.
//
// Q: How does object editing work?
//
// A: One way to think of this is that in the editor, you're placing
// spawners, not objects. Each spawner must be tile-aligned, because
// it's only a tile editor. Each tile (stack of layers) gets
// an associated set of properties, and it's up to you to
// determine what properties should appear for a given tile,
// based on e.g. the spawners that are in it.
//
// Q: How are properties themselves handled?
//
// A: All properties, regardless of UI behavior, are internally floats.
// Each tile has an array of floats associated with it, which is
// passed back to you when drawing the tiles so you can draw
// objects appropriately modified by the properties.
//
// Q: What if I want to have two different objects/spawners in
// one tile, both of which have their own properties?
//
// A: Make sure STBTE_MAX_PROPERTIES is large enough for the sum of
// properties in both objects, and then you have to explicitly
// map the property slot #s to the appropriate objects. They'll
// still all appear in a single property panel; there's no way
// to get multiple panels.
//
// Q: Can I do one-to-many linking?
//
// A: The library only supports one link per tile. However, you
// can have multiple tiles all link to a single tile. So, you
// can fake one-to-many linking by linking in the reverse
// direction.
//
// Q: What if I have two objects in the same tile, and they each
// need an independent link? Or I have two kinds of link associated
// with a single object?
//
// A: There is no way to do this. (Unless you can reverse one link.)
//
// Q: How does cut & paste interact with object properties & links?
//
// A: Currently the library has no idea which properties or links
// are associated with which layers of a tile. So currently, the
// library will only copy properties & links if the layer panel
// is set to allow all layers to be copied, OR if you set the
// "props" in the layer panel to "always". Similarly, you can
// set "props" to "none" so it will never copy.
//
// Q: What happens if the library gets a memory allocation failure
// while I'm editing? Will I lose my work?
//
// A: The library allocates all editor memory when you create
// the tilemap. It allocates a maximally-sized map and a
// fixed-size undo buffer (and the fixed-size copy buffer
// is static), and never allocates memory while it's running.
// So it can't fail due to running out of memory.
//
// Q: What happens if the library crashes while I'm editing? Will
// I lose my work?
//
// A: Yes. Save often.
//
//
// HOW TO COMPILE
//
// This header file contains both the header file and the
// implementation file in one. To create the implementation,
// in one source file define a few symbols first and then
// include this header:
//
// #define STB_TILEMAP_EDITOR_IMPLEMENTATION
// // this triggers the implementation
//
// void STBTE_DRAW_RECT(int x0, int y0, int x1, int y1, uint color);
// // this must draw a filled rectangle (exclusive on right/bottom)
// // color = (r<<16)|(g<<8)|(b)
//
// void STBTE_DRAW_TILE(int x0, int y0,
// unsigned short id, int highlight, float *data);
// // this draws the tile image identified by 'id' in one of several
// // highlight modes (see STBTE_drawmode_* in the header section);
// // if 'data' is NULL, it's drawing the tile in the palette; if 'data'
// // is not NULL, it's drawing a tile on the map, and that is the data
// // associated with that map tile
//
// #include "stb_tilemap_editor.h"
//
// Optionally you can define the following functions before the include;
// note these must be macros (but they can just call a function) so
// this library can #ifdef to detect if you've defined them:
//
// #define STBTE_PROP_TYPE(int n, short *tiledata, float *params) ...
// // Returns the type of the n'th property of a given tile, which
// // controls how it is edited. Legal types are:
// // 0 /* no editable property in this slot */
// // STBTE_PROP_int /* uses a slider to adjust value */
// // STBTE_PROP_float /* uses a weird multi-axis control */
// // STBTE_PROP_bool /* uses a checkbox to change value */
// // And you can bitwise-OR in the following flags:
// // STBTE_PROP_disabled
// // Note that all of these are stored as floats in the param array.
// // The integer slider is limited in precision based on the space
// // available on screen, so for wide-ranged integers you may want
// // to use floats instead.
// //
// // Since the tiledata is passed to you, you can choose which property
// // is bound to that slot based on that data.
// //
// // Changing the type of a parameter does not cause the underlying
// // value to be clamped to the type min/max except when the tile is
// // explicitly selected.
//
// #define STBTE_PROP_NAME(int n, short *tiledata, float *params) ...

//
// #define STBTE_PROP_MIN(int n, short *tiledata) ...your code here...
// #define STBTE_PROP_MAX(int n, short *tiledata) ...your code here...
// // These return the allowable range for the property values for
// // the specified slot. It is never called for boolean types.
//
// #define STBTE_PROP_FLOAT_SCALE(int n, short *tiledata, float *params)
// // This rescales the float control for a given property; by default
// // left mouse drags add integers, right mouse drags adds fractions,
// // but you can rescale this per-property.
//
// #define STBTE_FLOAT_CONTROL_GRANULARITY ... value ...
// // This returns the number of pixels of mouse motion necessary
// // to advance the object float control. Default is 4
//
// #define STBTE_ALLOW_LINK(short *src, float *src_data, \
// short *dest, float *dest_data) ...your code...
// // this returns true or false depending on whether you allow a link
// // to be drawn from a tile 'src' to a tile 'dest'. if you don't
// // define this, linking will not be supported
//
// #define STBTE_LINK_COLOR(short *src, float *src_data, \
// short *dest, float *dest_data) ...your code...
// // return a color encoded as a 24-bit unsigned integer in the
// // form 0xRRGGBB. If you don't define this, default colors will
// // be used.
//
//
// [[ support for those below is not implemented yet ]]
//
// #define STBTE_HITTEST_TILE(x0,y0,id,mx,my) ...your code here...
// // this returns true or false depending on whether the mouse
// // pointer at mx,my is over (touching) a tile of type 'id'
// // displayed at x0,y0. Normally stb_tilemap_editor just does
// // this hittest based on the tile geometry, but if you have
// // tiles whose images extend out of the tile, you'll need this.
//
// ADDITIONAL CONFIGURATION
//
// The following symbols set static limits which determine how much
// memory will be allocated for the editor. You can override them
// by making similiar definitions, but memory usage will increase.
//
// #define STBTE_MAX_TILEMAP_X 200 // max 4096
// #define STBTE_MAX_TILEMAP_Y 200 // max 4096
// #define STBTE_MAX_LAYERS 8 // max 32
// #define STBTE_MAX_CATEGORIES 100
// #define STBTE_UNDO_BUFFER_BYTES (1 << 24) // 16 MB
// #define STBTE_MAX_COPY 90000 // e.g. 300x300
// #define STBTE_MAX_PROPERTIES 10 // max properties per tile
//
// API
//
// Further documentation appears in the header-file section below.
//
// EDITING MULTIPLE LEVELS
//
// You can only have one active editor instance. To switch between multiple
// levels, you can either store the levels in your own format and copy them
// in and out of the editor format, or you can create multiple stbte_tilemap
// objects and switch between them. The latter has the advantage that each
// stbte_tilemap keeps its own undo state. (The clipboard is global, so
// either approach allows cut&pasting between levels.)
//
// REVISION HISTORY
// 0.38 fix warning
// 0.37 fix warning
// 0.36 minor compiler support
// 0.35 layername button changes
// - layername buttons grow with the layer panel
// - fix stbte_create_map being declared as stbte_create
// - fix declaration of stbte_create_map
// 0.30 properties release
// - properties panel for editing user-defined "object" properties
// - can link each tile to one other tile
// - keyboard interface
// - fix eraser tool bug (worked in complex cases, failed in simple)
// - undo/redo tools have visible disabled state
// - tiles on higher layers draw on top of adjacent lower-layer tiles
// 0.20 erasable release
// - eraser tool
// - fix bug when pasting into protected layer
// - better color scheme
// - internal-use color picker
// 0.10 initial release
//
// TODO
//
// Separate scroll state for each category
// Implement paint bucket
// Support STBTE_HITTEST_TILE above
// ?Cancel drags by clicking other button? - may be fixed
// Finish support for toolbar at side
