I'm converting an IrisGL program to be a mixed model application.
In the IrisGL application we did the above and it worked fine, but
now using the glxMDraw widget my images are not keeping their aspect
ratio like they used to, but rather they're getting squashed when
I resize the window.
If I am using a glxMDraw widget and, say, it is 100 by 500 pixels,
can I do a viewport(0, 500, 0, 500)? That is, will I be able
to draw to a square region (500x500) and have the window clip the image?
Or does my viewport command really get turned into:
