[PATCH v2 0/1] MR3568: gdiplus: implement PixelOffsetModeHighQuality for GdipDrawImagePointsRect

[Bartosz Kosiorek (＠gang65)]

After investigation, it looks like the PixelOffsetModeHalf/PixelOffsetModeHighQuality is using floating point numbers, while PixelOffsetModeNone/PixelOffsetModeHighSpeed is using integers to calculate bitmap colours. 

After using floating numbers, most tests are passing now.
