Jelle Raaijmakers bd55e85027 LibGfx: Implement Gfx::AlphaType for SkiaPainter ...

Always assuming unpremultiplied color data only worked for PNGs (which
are specced as unpremultiplied) and bitmaps with alpha set to 100%.
Properly propagate the Gfx::AlphaType of a bitmap to Skia.

The reference tests were updated to reflect this change, but visually
it's practically impossible to see the difference. A new test was added
to clearly expose this issue.

Fixes #1104
