Detailed Description

GrAHardwareBufferImageGenerator allows to create an SkImage attached to an existing android native hardware buffer. A hardware buffer has to be created with AHARDWAREBUFFER_USAGE_GPU_SAMPLED_IMAGE usage, because it is bound to an external texture using an EGLImage. The image generator will keep a reference to the hardware buffer for its lifetime. A hardware buffer can be shared between processes and same buffer can be used in multiple GPU contexts. To implement certain features like tiling, Skia may copy the texture to avoid OpenGL API limitations.
