- clamp the max. radius to 128, as the software path does
- use a more accurate radius-to-sigma conversion (0.6 instead of 0.6666)
- make SampleBlur derive from SampleView, not SkView, so benchmark mode ('f')
works
- implement a new BigBlur sample to test large radii

blur were being clipped to the size of the output window, causing the blurred
primitive to be truncated if the FBO was larger than the output window. Clip
them to the srcRect instead, and restore when done.

skdiff --chromium-release baseDir outputDir
skdiff --chromium-debug baseDir outputDir
where baseDir is typically ../chromium/src.
Handles Chromium/WebKit layout tests: recursively traverses the
layout-test-results directory and compares -expected and -actual PNGs,
building a webpage showing the two images, their difference image,
and statistics, sorted by % of pixels difference. Respects all the
standard skdiff flags.
Also changes command line options named with words from starting with
a single hyphen to starting with two, falling in line with standards:
--threshold, --sortbymismatch, etc.

1. better support reading from multiple input directories, and
2. allow filenames to differ between reference and novel images.

- convolveRect() is too low-level; made it private and exposed convolveInX() and
convolveInY() instead
- added GrAutoTextureEntry to automatically unlock a texture entry
- the clipping and bounder checks were returning false from
drawWithGPUMaskFilter(), causing the software blur to kick in; return true
instead
- the Windows build was giving a spurious warning about reading an uninitialized
variable; rearrange the code to fix it

Conditionally #defines SK_RESTRICT to be __restrict on Win32;
this successfully compiles in VS2008.

Implements the remaining blur types (inner, outer, solid) in the
GPU-based Gaussian blur. They are implemented using a post-upsampling blending
pass. Also includes some code cleanup and comments.

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

in SkDrawPaint::add(); check the pointer when it's used to avoid
dereferencing NULL.
