From b8d6e088590160f1198110c2371b802c1d541a36 Mon Sep 17 00:00:00 2001 From: erikchen Date: Tue, 9 Feb 2016 13:30:55 -0800 Subject: [PATCH] skia: Add support for CHROMIUM_image backed textures. I created a new abstract base class TextureStorageAllocator that consumers of Skia can subclass and pass back to Skia. When a surface is created with a pointer to a TextureStorageAllocator, any textures it creates, or that are derived from the original surface, will allocate and deallocate storage using the methods on TextureStorageAllocator.
