Package: iceweasel
Version: 3.5.12-2
Severity: normal
Tags: patch

Upscaled images looks ugly. Here is what is written about it in
/iceweasel-3.5.12/gfx/src/thebes/nsThebesImage.cpp line 672:

// See bug 324698.  This is a workaround for EXTEND_PAD not being
// implemented correctly on linux in the X server.
//
// Set the filter to CAIRO_FILTER_FAST --- otherwise,
// pixman's sampling will sample transparency for the outside edges
// and we'll
// get blurry edges.  CAIRO_EXTEND_PAD would also work here, if
// available
//
// But don't do this for simple downscales because it's horrible.
// Downscaling means that device-space coordinates are
// scaled *up* to find the image pixel coordinates.
//
// deviceToImage is slightly stale because up above we may
// have adjusted the pattern's matrix ... but the adjustment
// is only a translation so the scale factors in deviceToImage
// are still valid.

This workaround  makes upscaled images look really  bad, but it is not
needed anymore! For quite long  time everything works fine without it,
i.e. X  server was fixed I  guess. I've been patching  (disabling this
workaround)  and building  iceweasel  myself for  quite sometime,  and
images look way  better. So please include this patch!  Just got tired
building iceweasel myself. Many users  like me with high resolution of
the screen need to scale web-pages, but then in the current version of
iceweasel/firefox images looks really ugly.
