How does one draw an open polygon using whether OSG API's or OpenGL
I know how to draw, for instance, a filled rectangle, but how do I draw a
filled rectangle with a hole inside?

My data structures are stored as follows: a vector of the outward polygon's
vertices in clockwise order (e.g. filled rectangle), and then a vector of
"holes" stored as a vector of vertices in counter-clockwise order
