Profiling data (Inverted call stack)

I did some profiling on my -O2 wine using perf (bfd version). Results attached.

To functions eat most of the time:

blend_rects_8888 calling into blend_argb (inlined)

GdipDrawImagePointsRect calling into resample_bitmap_pixel
(InterpolationModeNearestNeighbor) calling into sample_bitmap_pixel.

No idea how either could be meaningfully improved.
