630114 - Use gfxPattern::EXTEND_PAD instead of the default (gfxPattern::EXTEND_NONE)

Status: RESOLVED WONTFIX

(Core :: SVG, defect)

Description

[Jonathan Watt [:jwatt]]

Bas tells me that gfxPattern::EXTEND_NONE (the default) isn't hardware accelerated, and we would get a perf boost if we were to use gfxPattern::EXTEND_PAD instead. Basically we should look at the locations where we use PopGroup and PopGroupToSource and consider whether we can paint the result using EXTEND_PAD.

Of course using EXTEND_PAD would require that we have a clip in place that restricts painting to the dimensions of the offscreen that we're painting.

There is no PAD any more.
