[TextureMapper] shrinked blur radius of drop-shadow shouldn't exceed
GaussianBlurMaxRadius
https://bugs.webkit.org/show_bug.cgi?id=265659
Reviewed by Michael Catanzaro.
TextureMapper::applyDropShadowFilter shrinks a source texture and a
blur radius of drop-shadow before applying a blur filter. The
downscaling ratio is based on the blur radius so that the shrinked
blur radius doesn't exceed GaussianBlurMaxRadius. However, the
calculation wasn't correct. it could slightly exceed
GaussianBlurMaxRadius if a blur radius is very large.
* LayoutTests/compositing/filters/drop-shadow-large-blur-radius-expected.html:
Added.
* LayoutTests/compositing/filters/drop-shadow-large-blur-radius.html: Added.
* Source/WebCore/platform/graphics/texmap/TextureMapper.cpp:
Use std::min to radius as well as TextureMapper::applyBlurFilter does.
