The comment change here looks a little odd, because previously
it was a matched pair with the one in the other half of the #ifdef:
one side is "for OS X >= 10.4" and the other "for < 10.4". After
this change we have a mismatch. In fact it doesn't matter because
we don't support any OSX version that old any more anyway.

I think we should delete the whole #ifdef...#else...#endif block
here, and replace it with just the
              CGColorSpaceCreateWithName(kCGColorSpaceSRGB),
              kCGBitmapByteOrder32Little | kCGImageAlphaNoneSkipFirst,

lines, because we dropped PPC support a long long time ago.
(And we don't need any comment about OSX version if we do that.)

thanks

This change also removes the legacy color space specification for
PowerPC.

Doesn't apply cleanly against git master branch, please rebase & resend.

take care,

Still doesn't apply, looks like a conflict with one of your other
(meanwhile merger) patches.  Those kind of changes are best submitted
as patch series.

take care,
