Description Andreas Kling 2010-10-29 05:55:47 PDT
We're currently doing some unnecessary stuff, like creating a black QBrush and throwing it away, and using setRenderHint() instead of setRenderHints().

Maybe add a comment about this in the code so that noone adds setPlatform in the future.

> WebCore/platform/graphics/qt/GraphicsContextQt.cpp:238
> +    // use the default the QPainter was constructed with

Comments start with capital letter and ends with a dot, you should know that by now :-)

> WebCore/platform/graphics/qt/GraphicsContextQt.cpp:257
> +    // solidColor is initialized with the fillColor()

Again! </3
