render: sprite: Allow passing custom transformation matrices.

* chickadee/render/sprite.scm (draw-sprite-unbatched,
draw-sprite-batched): Replace 'scale' and 'rotation' arguments with a
'matrix' argument.
(sprite-batch-add!): Ditto. Also, correctly transform sprite
vertices.  This was previously not handling rotations properly.
(%default-offset): New variable.
(draw-sprite, draw-nine-patch): Change default values for 'rotation'
and 'scale'.  Add 'matrix' and 'offset' arguments.
* chickadee/render/font.scm (%default-offset): New variable.
(draw-text): Change default values for 'rotation' and 'scale'.  Add
'offset' and 'matrix' arguments.
