[TexMap] Painting into area of composited tile not cleared
https://bugs.webkit.org/show_bug.cgi?id=112268

Reviewed by Kenneth Rohde Christiansen.

Clip painting to the area that has been cleared, so we
do not accidentally overpaint other areas.

Can be observed in ManualTests/scrollbars/scrollbars-in-composited-layers.html.
