| GPU | | Efficient Clipping on GPU | ||
| | | Mozilla renders a page as a series of layers that are composited together, using the GPU when possible. Clipping and opacity are properties on individual layers. The current GPU layer clipping code requires the clip to be an axis-aligned rectangle, and in other cases we are allocating an intermediate surface and rendering to that (transformations), or handling the render in software (SVG). We should be able to handle this using the stencil buffer or similar. | ||

| When | | Mozilla renders a page as a series of layers that are composited together, using the GPU when possible. When Mozilla separates an image into a dedicated layer we have two copies of the data, one in system memory (owned by imglib) and one as a texture. We can teach imglib about this second copy and free the system memory one in some cases to save memory usage. This is particularly useful for mobile (Android) where image scaling is much cheaper on the GPU, but the memory cost of two copies will hurt. | ||
