[PATCH v9 0/4] MR2864: gdiplus: Improve performance of GdipDrawImagePointsRect

[Bartosz Kosiorek (＠gang65)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=53947

Improve performance of GdipDrawImagePointsRect by:
1. avoiding multiplication and use addition where it is possible.
2. avoid calculating `GdipInvertMatrix` if it is not used
It gives noticible speed improvement.

I divided MR to several commits, to better undestand what is going on.

Application for testing (it needs logo.jpg file):

      gdiplus: use float increment instead of calculation to impove perf
      gdiplus: use iterator instead calculate pointer position every time
