Log Message
Try to fix assertion failures on ports that do not support kerning and ligatures on the fast
code path after r131365.
* platform/graphics/WidthIterator.cpp:
(WebCore::applyFontTransforms): Changed the early return condition to not bother with 1-glyph
sequences.
* platform/graphics/WidthIterator.h:
(WebCore::WidthIterator::shouldApplyFontTransforms): Changed to return false if the run is
shorter than 2 characters.
