	Compositor-reported translation to apply when drawing promotedTexture() on top of bg/fg. Reflects the delta between the bitmap's rasterize-time DOM transform and the entity's current DOM transform — i.e. how far the user has dragged since the bitmap was last stamped.

Detailed Description

Owns the GL textures the advanced editor uses for flat, overlay, and composited presentation.

The cache is intentionally dumb: callers decide when textures should update; this class only owns the texture names, uploads pixel buffers, and tracks the currently-valid dimensions.

The documentation for this class was generated from the following file:

donner/editor/GlTextureCache.h
