render: Change texture origin to top-left.
This is a pretty big change, but hopefully for the best as this aligns with graphics programs and the glTF standard that uses a top-left origin. We can keep using a lower-left origin for vertices, though. * chickadee/render/texture.scm (surface->texture): Stop flipping pixel rows. * chickadee/render/sprites.scm (draw-sprite-unbatched, sprite-batch-add!, draw-nine-patch*): Adjust texture y-coordinates. * chickadee/render/font.scm (parse-fnt): Stop inverting y coordinates. * chickadee/render/tiled.scm (load-tile-map): Stop inverting tile ids.
