Reviewed by Tim Horton.

Source/WebCore:

Make the m_visibleTileWashLayer more useful by showing it for all
layers with transforms, not just tiled layers. This is a debugging
layer normally disabled, but enabled by #defining VISIBLE_TILE_WASH.

LayoutTests:

Add some tests of the GraphicsLayerCA visibleRect for simple cases.

Skip these tests on platforms that don't log layer visible rects
(all non-Mac).
