CoordinatedGraphics: Fix integer rounding when computing pixel alignment
https://bugs.webkit.org/show_bug.cgi?id=122565
Patch by Sergio Correia <[email protected]> on 2013-10-09
Reviewed by Noam Rosenthal.
Source/WebCore:
Replace roundedIntRect call in computePixelAlignment() with enclosingIntRect,
so that very small rectangles (after content scaling) don't appear to be empty,
creating a crash later.
Test: transforms/3d/general/rotate-45-degrees-long-inner-text-in-dt.html
* platform/graphics/texmap/coordinated/CoordinatedGraphicsLayer.cpp:
(WebCore::CoordinatedGraphicsLayer::computePixelAlignment):
LayoutTests:
Added test that rotates 45 degrees a very long text in a dt tag that
might crash the browser depending on how it handles the integer
rounding when computing pixel alignment.
* transforms/3d/general/rotate-45-degrees-long-inner-text-in-dt-expected.txt: Added.
* transforms/3d/general/rotate-45-degrees-long-inner-text-in-dt.html: Added.
