Please be more specific so I don't answer the wrong question. 
(Why not in D? Why a C API? Other?)

And re: hardware acceleration of Quartz2D ... at least up to 
10.12, I see no evidence of that in my testing. Compared to 
Direct2D on Windows, native Quartz2D drawing on a 5k iMac (i7 
6700k) over a large enough area is noticeably sluggish.

I would be interested to know exactly what API functions are 
supposed to be accelerated. Ever since QuartzGL went away, there 
doesn't seem to be any public information about what, if 
anything, is GPU-assisted. Of course I'm talking about pure 
Quartz2D (Core Graphics) here, nothing else.
