From 92098e691f10a010e7421125ba4d44c02506bb55 Mon Sep 17 00:00:00 2001 From: erikchen Date: Thu, 4 Feb 2016 12:03:07 -0800 Subject: 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.
