Some tests were using source surfaces created as ARGB32 even though all alpha values are entirely opaque. This meant these tests were triggering more fallbacks than strictly necessary for what the tests are ttrying to do.

/* Bug history
|
|
*
|
|
* 2005-04-11 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* It appears that calling cairo_show_surface after cairo_translate
|
|
* somehow applies the translation twice to the surface being
|
|
* shown. This is pretty easy to demonstrate by bringing up xsvg on
|
|
* an SVG file with an <image> and panning around a bit with the
|
|
* arrow keys.
|
|
*
|
|
* This is almost certainly a regression, and I suspect there may be
|
|
* some interaction with the fix for move-to-show-surface.
|
|
*
|
|
* 2005-04-12 Carl Worth <cworth@cworth.org>
|
|
*
|
|
* I committed a fix for this bug today.
