* Improve GPU blur performance by clearing only when necessary. This gives aGravatar senorblanco@chromium.org2011-07-22
| | | | | | | | | | | | | | | | | | 1.8X speedup on the Blurs sample, and 2.3X on the BigBlur sample. We don't need to clear while downsampling, since each step reads only the pixels written in the previous step. We can avoid destination clears before convolution by disabling blending. We also don't need to clear when upsampling, since the upsample step also only reads pixels written by the convolution. The only clears we then need to do are on each side of the srcRect used for convolution, and a 1-pixel border for bilinear upsampling. Since our srcRect is always offset to (0, 0), we only need to clear on the right and bottom.

* Adding the notion of a volatile bitmap to SkBitmap. Gravatar junov@google.com2011-06-30
| | | | | | | | | | | | | | | | | Volatility is a hint that indicates that the contents of a bitmap are ephemeral. SkGpuDevice will not preserve volatile bitmaps in its texture cache, and will use textures from a pool of keyless (recyclable) textures to avoid the performance hit of texture allocation and release. A subsequent change is required in webkit in order to take advantage of this optimization. putImageData, and other methods that create temporary bitmaps will have to mark their bitmaps as volatile. before rendering them through skia. git-svn-id: http://skia.googlecode.com/svn/trunk@1769 2bbb7eff-a529-9590-31e7-b0007b416f81
