Jeff Muizelaar a1c7482bc4 Bug 1131446. mFrameHasNoAlpha is mostly pointless. r=seth
Starting with bug 391583 we detect whether a png image has any transparency
during decode. I don't think this is worth doing anymore. We choose the format
of image based on the png header, that should be sufficient for the performance
improvement we desire from opaque images. This gets us faster image decoding.
