| michael@0 | 25 | * A TextureClient implementation based on android::GraphicBuffer (also referred to |
| michael@0 | 26 | * as "gralloc"). |
| michael@0 | 27 | * |
| michael@0 | 28 | * Gralloc lets us map texture data in memory (accessible through pointers) |
| michael@0 | 29 | * and also use it directly as an OpenGL texture without the cost of texture |
| michael@0 | 30 | * uploads. |
| michael@0 | 31 | * Gralloc buffers can also be shared accros processes. |
