Properly scope ScopedPlatformPaint so that the native drawing layer and Skia are in agreement on the state of the pixels. Also fix Windows to not return completely transparent bitmaps when the source image has color depth < 32 bpp.

BUG=86085
TEST=Copy an image from MS Paint and paste it into Gmail using 32bpp for the display color depth.
