michael@0: # Reftests for downscaling
michael@0: #
michael@0: # Downscaling can be a lossy process, so a bit of mismatch is acceptable here,
michael@0: # as long as it's barely noticable visually. When necessary, this can be
michael@0: # explicitly allowed via 'fuzzy'/'fuzzy-if' annotations.
michael@0: #
michael@0: # IMPORTANT: For robustness, each test should be listed *twice* in this
michael@0: # manifest -- once with the high quality downscaling pref disabled, and once
michael@0: # with this pref enabled. The pref is set via "default-preferences", so
michael@0: # simply appending a new test to the lists below each of those lines should be
michael@0: # sufficient.
michael@0: #
michael@0: # Also note that Mac OS X has its own system-level downscaling algorithm, so
michael@0: # tests here may need Mac-specific "fuzzy-if(cocoaWidget,...)" annotations.
