I know I asked this before, but the only response I really got was not exactly
Would it make sense to consider doing certain tasks (nearest-neighbor image
scaling is the one that I was interested in) not through Render at all, if it's
known to be possible?
See https://bugzilla.mozilla.org/show_bug.cgi?id=371892 for details. Note that
the issue is also reproducible with FC6, so I'm not sure that the exact Render
version involved is relevant. The crux of the matter is that even
nearest-neighbor scaling with Render is a lot slower than XlibRectStretch, and
over here is even slower than client-side scaling...
Basically, I don't see X server GPU acceleration of Render actually making its
way to the install base this year, which means that while it'll be nice to have
in the future we can't depend on it right now to resolve performance issues.
Sorry to harp on this, but this is actually making my daily web browsing a
pretty painful experience, and I'd rather not put users through it. ;)
