Subject: Patch to put back dynamic OpenGL loading for MPW
I sent a patch a while ago that removes dynamic OpenGL loading for
Macintosh Programmer's Workshop. Dynamic loading DOES actually work
when an SDL program is built with MPW, it just has to be set up for it.
(Whoops!!) This is the ideal way to get OpenGL extensions to work,
which D2X uses quite a few of.
This patch puts dynamic loading back in SDL for Mac OS 9. It applies to
current CVS. I noticed that two members need to be set when
DrawSprocket is used.
