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

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=136163

`dst_area` is an optimization to limit the number of pixels rendered. It's not meaningful for this to have a non-integer value.

I will investigate it further. I think I need improve tests first

I assume the documented function is what it actually does, basically translating device coordinates by half a pixel on each axis. That shouldn't require a separate implementation for each drawing function.
