Share glyph and icon caches Use the same texture atlases to back both the glyph and icon caches, and unify their sizes and management. Store big glyphs in separate textures, so all atlases have the same size. Tweak some of the eviction parameters. We share the caches across all GL contexts on a display, unless the GSK_NO_SHARED_CACHES env var is set. 2019-06-04 21:27:09 +00:00			`int ref_count;`
