This CL clarifies what is going on in the GrDrawOpAtlas and GrAtlasGlyphCache. For the GrDrawOpAtlas: At creation time all the allowed pages are created (with their backing GrTextureProxies) but they aren't instantiated. The GrDrawOpAtlas::instantiate call is called in preFlushCB and allocates any pages known to be needed at the start of flush GrDrawOpAtlas::addToAtlas is called at flush time and, if a new page is activated, will instantiated it at that time. During compaction, an unused page will be deInstantiated but its Plots and backing GrTextureProxy will remain alive. The GrAtlasGlyphCache reflects the changes to the GrDrawOpAtlas It now carries a GrProxyProvider for when it needs to create an atlas It passes in a GrResourceProvider* at flush time to allow instantiation. It does not, yet, allocate that GrDrawOpAtlases it might ever require.
