senorblanco@chromium.org 027de5f922 GPU-based Gaussian blur. This is a first stab at implementing a GPU-based Gaussian blur in Ganesh. The convolution shader is implemented as a new filtering mode. There are several known issues: - no support for blur types other than "normal" - FBO truncation problem at high zoom values - uses bilinear for upsampling instead of Mitchell Review URL: http://codereview.appspot.com/4645082/ git-svn-id: http://skia.googlecode.com/svn/trunk@1830 2bbb7eff-a529-9590-31e7-b0007b416f81	2011-07-08 18:03:33 +00:00

This is a first stab at implementing a GPU-based
Gaussian blur in Ganesh.  The convolution shader is implemented as a new
filtering mode.  There are several known issues:

- no support for blur types other than "normal"
- FBO truncation problem at high zoom values
- uses bilinear for upsampling instead of Mitchell
