0.22.0

This release comes with a major change to everything in agb::display. Mostly built around the new GraphicsFrame
used to show both backgrounds and objects to the screen. See the newly expanded book
which covers many topics including advanced articles for more exciting graphical effects and completed
tutorial.

You can now also try all the examples online on your browser, including modifying the
code and seeing how that changes the behaviour of the example!

Added

• GraphicsFrame is now how you manage what gets displayed to the screen. Both for backgrounds and objects.
• Lots more examples.
• The crate is 100% documented!
• #[agb::entry] now produces code which is compatible with rust 2024.
• Introduced agb::display::{Rgb15, Rgb} to represent colours and allow for basic interpolation and conversion.
• You can now pass any constant expression to the num! macro.
• Added round methods for Num and Vector2D that rounds towards the nearest integer.
• Added clamp_point and corner methods to Rect.
• Added width and height to TileData to track the original size of your backgrounds.
• Added an eprintln!() macro which prints at error level for mgba.
• More num_traits have been implemeted for Num<I, N>.
• The template now includes extern crate alloc; to avoid any confusion about whether alloc is supported.
• Blending and windows now work with affine backgrounds as well as regular backgrounds
• Added animation_frame to Tag to allow for more efficient sprite animations.
• You can now write your own doc tests using the agb::doctest macro.

Changed

• The VRamManager is now global, accessed via the VRAM_MANAGER.
• You no longer need to pick a tiled mode, instead this is managed by the GraphicsFrame.
• Blending, windows and DMA are managed via the GraphicsFrame.
• DMA is now entirely safe and is managed by HBlankDma.
• The agb::display module has been flattened quite significantly.
• InfiniteScrolledMap now takes the tile generation function in set_pos rather than in the constructor.
• There are getters and setters for almost all properties in RegularBackground and AffineBackground.
• Affine tile allocation is now much more reliable, rather than it basically being pure luck whether a tile successfully displays.
• Where agb used to accept u16 values for colours, it now expects the new Rgb15 type to avoid type confusion.
• The mixer now uses SoundData rather than &[u8] sound effects and music.
• In debug mode, Num will now panic if you're multiplying or dividing when it has too much precision set.
• Palette16 is now in the agb::display module.
• You get the graphics from gba.graphics rather than gba.display.graphics.
• DynamicTiles are now automatically freed when they are dropped, so you don't need to manually manage that memory any more.
• Font rendering for backgrounds and objects have been unified via the Layout struct, and are rendered using the new
  ObjectFontRenderer and BackgroundFontRenderer. Both fully support colour changes and other arbitrary tags.
• AffineMatrixInstance is now AffineMatrixObject and the existing AffineMatrixObject has been removed to simplify the conversion.
• AffineMatrix is now generic on the integer type.
• sin and cos for Num<I, N> has been improved to use a look-up table with linear interpolation rather than a 3rd order polynomial.
• Object's set_position() function was renamed to set_pos().
• include_background_gfx! now requires a mod keyword before the module name.
• inculde_aseprite! now creates static variables for each tag rather than using constant string matching.
• Unmanaged objects are now managed by the GraphicsFrame rather than OamIterator and now only make their changes when .commit() is called.
• ObjectUnmanaged is now Object.
• Affine objects are now a separate type ObjectAffine.
• For compatibility with rust 2024, rng::gen() has been renamed to rng::next_u32().

Removed

• Removed bitmap modes. These were accidentally unsound and don't play well with objects or other tiled backgrounds. Some thought needs to go
  into the API to bring these back.
• Removed the dmg audio module. It will return in future but with a better thought out API which will work together with the existing mixer.
• Removed VRamManager.set_background_palette_raw since it is actually unsafe and didn't work as intended for smaller palettes in release mode.
• Removed the syscall module and put the useful halt method in agb::halt().
• Removed the mgba module since you should do all printing via the println!() macro.
• Removed 'managed' objects. The new GraphicsFrame uses a similar paradigm to the old 'unmanaged objects'. But these are now just Object.
• Removed mixer.enable(). This is now done by default so you just don't need to call it.
