What is Gralloc in Android?

Gralloc is a type of shared memory that is also shared with the GPU. A Gralloc buffer can be written to directly by regular CPU code, but can also be used as an OpenGL texture. Gralloc is part of Android, and is also part of B2G. Gralloc buffers are represented by objects of the class android::GraphicBuffer.
