Are there automated tests that verify that Wine's drawing operations produce the same visual output as in Windows?

[Alexander Almaleh]

While testing the Polygon() function for my bug report -
https://bugs.winehq.org/show_bug.cgi?id=36891, I used a test program that
performs a Polygon() operation on a memory device context, and then saves
it to a bitmap - i.e. a *.bmp file.

I then compared the bitmaps produced under Windows and Wine using a program
I wrote in Qt, that just compares width/height, and then makes a
pixel-by-pixel comparison (and the Polygon() function did indeed produce a
slightly different bitmap).

Since this process can be easily automated, I'm wondering if such a
framework is already being used? If not, I could probably make a sample
test program and image comparison tool, if anyone is interested.

It would be fairly easily to spot all kinds of bugs in the drawing
functions using such a testing system.
