op: correctly initialize GSactive.

The graphics state can be pushed and popped. As such, in addition to the stack of the state, a pointer to the active state is kept at all times. While pushing and popping correctly updated the pointer, we were not previously initializing it on startup. While some PDFs - notably, ps2pdf output - worked without issues, other PDFs, which use the graphics state immediately, did not.

This commit resolves that issue by initializing GSactive to the initial graphics state when setting up the renderer.
