* before... it was buried within the compare() method at
* https://code.google.com/p/skia/source/browse/trunk/gm/gmmain.cpp?r=7289#305 .
*
* Apparently we need this, at least for bitmaps that are either:
* (a) destined to be written out as PNG files, or
* (b) compared against bitmaps read in from PNG files
* for the reasons described just above the force_all_opaque() method.
*
* Neglecting to do this led to the difficult-to-diagnose
* http://code.google.com/p/skia/issues/detail?id=1079 ('gm generating
* spurious pixel_error messages as of r7258')
*
* TODO(epoger): Come up with a better solution that allows us to
* compare full pixel data, including alpha channel, while still being
* robust in the face of transformations to/from PNG files.
* Options include:
*
* 1. Continue to call force_all_opaque(), but ONLY for bitmaps that
* will be written to, or compared against, PNG files.
* PRO: Preserve/compare alpha channel info for the non-PNG cases
* (comparing different renderModes in-memory)
* CON: The bitmaps (and hash digests) for these non-PNG cases would be
* different than those for the PNG-compared cases, and in the
* case of a failed renderMode comparison, how would we write the
* image to disk for examination?
*
* 2. Always compute image hash digests from PNG format (either
* directly from the the bytes of a PNG file, or capturing the
* bytes we would have written to disk if we were writing the
* bitmap out as a PNG).
* PRO: I think this would allow us to never force opaque, and to
* the extent that alpha channel data can be preserved in a PNG
* file, we could observe it.
* CON: If we read a bitmap from disk, we need to take its hash digest
* from the source PNG (we can't compute it from the bitmap we
* read out of the PNG, because we will have already premultiplied
* the alpha).
* CON: Seems wasteful to convert a bitmap to PNG format just to take
* its hash digest. (Although we're wasting lots of effort already
* calling force_all_opaque().)
*
* 3. Make the alpha premultiply/unpremultiply routines 100% consistent,
* so we can transform images back and forth without fear of off-by-one
* errors.
* CON: Math is hard.
*
* 4. Perform a "close enough" comparison of bitmaps (+/- 1 bit in each
* channel), rather than demanding absolute equality.
* CON: Can't do this with hash digests.
