        - fixed <rdar://problem/4002164> maps that include start and end
        location don't print right from maps.google.com

	I thought I checked this in yesterday but a ChangeLog conflict aborted my checkin
	without me noticing.

        * khtml/rendering/render_style.cpp:
        (RenderStyle::diff):
        flag name changed from _should_correct_text_color to _force_backgrounds_to_white

        * khtml/rendering/render_style.h:
        (khtml::RenderStyle::InheritedFlags::operator==):
        flag name changed from _should_correct_text_color to _force_backgrounds_to_white
        (khtml::RenderStyle::setBitDefaults):
        ditto
        (khtml::RenderStyle::forceBackgroundsToWhite):
        ditto, and method name changed too
        (khtml::RenderStyle::setForceBackgroundsToWhite):
        ditto

        * khtml/rendering/render_text.cpp:
        (InlineTextBox::paint):
        updated for name change; also, compare text against white instead of current bg color
        because we no longer actually modify the bg color (previously we would always set
        the bg color to white, so the result is the same)

        * khtml/xml/dom_docimpl.cpp:
        (DocumentImpl::recalcStyle):
        updated for name change

        * kwq/WebCoreBridge.mm:
        (-[WebCoreBridge styleSheetForPrinting]):
        removed this method
        (-[WebCoreBridge reapplyStylesForDeviceType:]):
        removed the code that called styleSheetForPrinting; we no longer use a stylesheet
        for this behavior.

        * khtml/rendering/render_box.cpp:
        (RenderBox::paintBackgroundExtended):
        If forceBackgroundsToWhite flag is set, convert background images and
        background colors to white background color with no background image.
