Draw to Tiled Canvas

[karai17]

Okay so here is the basic idea:

• Divide canvas into a grid
• Determine which cell(s) an element belongs to at any given time
• If any changes occur to an element, declare the cell(s) invalid
• Redraw any invalid cells

Anything that could affect the visual status of a cell would make it invalid, such as an animation, an element moving, an element scrolling, etc etc etc.

You should maybe call this "Spatial Dirty-Flagging" or something, I confused this with Tiled/mapeditor at first.

Doesn't have a potential to make all cells be marked as invalid any way do to a resize or something similar?

I haven't quite decided how I will do this yet, but I will have an option to flag the whole DOM for redrawing.
