@node Tilesets
@section Tilesets
In most 2D games, the game world is composed of many small,
rectangular pieces called tiles. In Sly, tilesets are used to
encapsulate a group of uniformly sized texture regions that come from
a single parent texture.
@anchor{2d tileset make-tileset}@defun make-tileset texture width height [#:margin] [#:spacing]
Return a new tileset that is built by splitting TEXTURE into tiles.
@end defun
@anchor{2d tileset load-tileset}@defun load-tileset filename width height [#:margin] [#:spacing]
Return a new tileset that is built by loading the texture at FILENAME
and splitting the texture into tiles.
