Revert 104566 - Source/WebCore: [Skia] Switch FEColorMatrix to use a skia-based implementation when
compiling with USE(SKIA).  This change will also switch the software
implementation of FEGaussianBlur to the skia implementation (ie.,
it removes the acceleration check).

Covered by svg/W3C-SVG-1.1/filters-color-01-b.svg and friends (will
need a rebaseline).

* WebCore.gypi:
Add FEColorMatrixSkia.cpp to the build.
* platform/graphics/filters/FEColorMatrix.h:
Add platformApplySkia().
* platform/graphics/filters/FEGaussianBlur.cpp:
(WebCore::FEGaussianBlur::platformApplySoftware):
Remove skia-specific code from FEGaussianBlur::platformApplySoftware().
* platform/graphics/filters/FEGaussianBlur.h:
Make platformApplySkia() virtual, and put it behind #if USE(SKIA).
* platform/graphics/filters/FilterEffect.cpp:
(WebCore::FilterEffect::apply):
Call out to platformApplySkia(), or fall back to
platformApplySoftware().
* platform/graphics/filters/FilterEffect.h:
Add platformApplySkia().
* platform/graphics/filters/skia/FEColorMatrixSkia.cpp: Added.
(WebCore::saturateMatrix):
(WebCore::hueRotateMatrix):
(WebCore::luminanceToAlphaMatrix):
(WebCore::FEColorMatrix::platformApplySkia):
Process color matrix effect, by calling out to generic matrix
version of SkColorMatrixFilter.
* platform/graphics/filters/skia/FEGaussianBlurSkia.cpp:
(WebCore::FEGaussianBlur::platformApplySkia):
Change the signature of FEGaussianBlur::platformApplySkia to be an
override of the new FilterEffect base class version.

LayoutTests: [chomium] Mark svg FEColorMatrix tests as needing new baselines.
