Merge r269837 - [TextureMapper] The edges of blur backdrop-filter look gradient tranparent
https://bugs.webkit.org/show_bug.cgi?id=218645
<rdar://problem/71356999>
Reviewed by Carlos Garcia Campos.
Source/WebCore:
The blur backdrop-filter needs a larger input image than an output
image. However, it's not easy to get a larger input image in the
edges of the windows. Cocoa port is doing extrapolation by
duplicating edges pixels of the input image which has the same
size with the output image (Bug 146215). Take the same approach.
* platform/graphics/texmap/TextureMapperLayer.cpp:
(WebCore::TextureMapperLayer::computeOverlapRegions): Don't
inflate the local bounding rect by the outsets for backdrop
layers.
* platform/graphics/texmap/TextureMapperShaderProgram.cpp:
(sampleColorAtRadius): Don't clamp 'coord'.
LayoutTests:
* platform/glib/css3/filters/backdrop/blur-input-bounds-expected.png: Added.
