After 267646@main improved gaussian blur filter, nothing drawn on
Raspberry Pi 3 which supports only GLES 2.0. The shader compiler
reports the following errors.
> Program log: ERROR:OPTIMIZER-3 (fragment shader, line 48) Support for for
> loops is restricted : right side of condition expression must be constant

* Source/WebCore/platform/graphics/texmap/TextureMapper.cpp: Zero-fills the
kernel.
* Source/WebCore/platform/graphics/texmap/TextureMapperShaderProgram.cpp:
Use a constant GAUSSIAN_KERNEL_MAX_HALF_SIZE for the for-loop of
applyBlurFilter and applyAlphaBlur for GLES<3.0 (ESSL 1.0)
