[UnifiedPDF] Odd gray backgrounds for short PDFs or when rubberbanding
https://bugs.webkit.org/show_bug.cgi?id=266746
rdar://119849112
Reviewed by Tim Horton.
Instead of painting the gray background into the scrolling tiles, put it on the
root layer as a GraphicsLayer
background color. Also size the root layer to fill the plugin view.
This makes the PDF tiles transparent where not covered by pages. We may in
future decide to make them opaque
and paint the color if necessary for performance.
