update triangle graphics reference tests with more variations

two primary goals with this change:

1. test triangle dimensions of varying widths, in preparation for
   upcoming simd per_pixel_triangle_2d changes. we want to ensure that
   scenarios where `width < 4` and `width % 4 != 0` continue to work
   fine after simd changes are done
2. test triangle rendering at various rotations, because i remember
   while testing fill rule changes, sometimes issues would only be
   visible at certain rotations. so this is mostly just useful for
   blended rendering methods, but still, is probably generally useful
   too ...
