DXX Raytracer is a fork of the DXX Retro project for Windows. DXX Raytracer uses modern raytracing techniques to update the graphics of the beloved retro game known as Descent.
g3_start_frame (used by automap among others) expects grd_curscreen->sc_aspect to be the pixel aspect ratio (i.e., 1_0f in a mode with square pixels) and not the screen aspect ratio
otherwise on a 16:9 screen automap shapes end up squished horizontally by a factor of 9/16
this change makes the sc_aspect setup code match what is done in other source ports (and also matches d1\arch\sdl\gr.c)
