proposed patch

Qt seems to be hard coding the base color for the frame view to brush(QPalette::Base) which is RGBA (255,255,255,255).
Since I couldn't change this value with html/css I hard coded it to baseColor = Color(0,0,255,128) for testing purposes in both trunk and my branch.
(If you know how I can affect this value with html/css pls let me know)

I ran QtLauncher trunk vs QtLauncher with the patch - result came out the same. See attached screenshot.

Here is the log from RenderBoxModelObject

baseColor RGBA 0,0,255,128
backgroundRect (0,0, 800,533)
bgColor RGBA 255,255,0,204
baseColor blended with bgColor RGBA 226,226,28,229
