Log Message
[Chromium] PlatformContextSkia::m_drawingToImageBuffer is not correctly set when using per-tile painting.
https://bugs.webkit.org/show_bug.cgi?id=81463
Patch by David Reveman <[email protected]> on 2012-03-17
Reviewed by James Robinson.
Call PlatformContextSkia::setDrawingToImageBuffer() from
SkPictureCanvasLayerTextureUpdater::prepareToUpdate so that sub-pixel
text rendering is not used incorrectly with per-tile painting.
No new tests.
