Author: Michael Drake <tlsa(a)netsurf-browser.org>
Commit: Michael Drake <tlsa(a)netsurf-browser.org>
PNG: Allow support for premultiplied alpha.
LibPNG doesn't support premultiplied alpha, so now that the core
supports it, we can't just say that the decoded PNG is in the
core bitmap format.
So we now say it's in the core pixel layout, and if it's opaque
we say it has the same premultipled alpha setting as core bitmaps
because the conversion is costly and makes no difference.
On the other hand if it is not opaque we now admit that it is
not premultipled alpha so it gets converted if needed.
