Yes, it is a pain. X is a moving target that seems to have no consensus solution beyond Cairo, which is slow...
MS seem to have had several stabs at this, and then seem to back off just before it actually comes to fruition - that certainly looks to be what happened with GDI+.
Their (MS) current scheme is Direct2D, but no one knows how to use that (apparently it plays nice with GDI and GDI+, and has a C API, but the examples I’ve seen don't intermix it with GDI or GDI+, and are written using their C++ API, which is in the usual hard-to-comprehend MS style... And which presumably is incompatible with the mingw* compilers that I use anyway...)

If I knew more about GL... that might be an option? 
At least it is widely supported on many platforms (even Apple, at least for now...) and *usually* has the benefit of some h/w acceleration.
