Remove hardcoded composition background color; use RenderStyle::compositionFillColor()

• Component: WebCore Misc.
• Status: RESOLVED WONTFIX

[Daniel Bates]

We should remove the hardcoded composition background color in InlineTextBox::paintCompositionBackground(), <http://trac.webkit.org/browser/trunk/Source/WebCore/rendering/InlineTextBox.cpp?rev=160951#L792> used by non-iOS ports. Instead we should always query RenderStyle::compositionFillColor() for this color. We may also need to support a platform-specific default composition background color.

I'm not convinced -webkit-composition-fill-color is needed at all, but if it is, we should support it everywhere.  If not, we should keep the RenderTheme part of this patch and remove the rest.

No need for these braces.

I can’t find any other code in this function that dereferences renderView(); do we have a solid guarantee that it’s non-null?

Is there a good reason to use m_node->document() rather than styledNode->document()?

Obviously didn’t belong here, but where is the tap color now?

Looks like we are leaving an extra blank line behind here.

Move the "&" next to Color, please.
