[Chromium] Mirror the resizer image of an RTL element when WTF_USE_RTL_SCROLLBAR is 1
https://bugs.webkit.org/show_bug.cgi?id=9223
Reviewed by Tony Chang.
This change mirrors a resizer image of an RTL element horizontall as Firefox
does. This change also mirrors its dragging behavior, i.e. draging the resizer
of an RTL element to the left side increases its width. (This feature is enabled
only when WTF_USE_RTL_SCROLLBAR is 1.)
Source/WebCore:
Test: platform/chromium/scrollbars/drag-rtl-resizer.html
* rendering/RenderLayer.cpp:
(WebCore::RenderLayer::resize): Mirrored the x coordinate of mouse positions
when mirroring a resizer.
(WebCore::RenderLayer::offsetFromResizeCorner): Returned the offset from the
bottom-left corner when rendering a resizer there.
(WebCore::RenderLayer::drawPlatformResizerImage): Mirrored the resizer bitmap
horizontally when rendering a resizer to the bottom-left corner.
LayoutTests:
* platform/chromium/scrollbars: Added.
* platform/chromium/scrollbars/drag-rtl-resizer-expected.txt: Added.
* platform/chromium/scrollbars/drag-rtl-resizer.html: Added.
