It finally dawned on me (after a less than subtle yet very helpful IM from
someone who shall remain nameless :-) that you're the LDGLite author. :-,
I've tried the LEdit mode, and gave up in frustration due to the slow redraw
(particularly with the text). I haven't formalized my list of (complaints?
bugs? dunno) concerning LDGLite, but I can if you want.
But there's one thing I've noticed that's in common with all LDraw tools
based on OpenGL, and that's that they're much slower than the original
LDraw.exe. Like by an order of magnitude. Please note that I am running
Windows 2000 on a non-3d-accelerated laptop, a notoriously slow combination
for OpenGL apps.

Good question. I couldn't find much on the libsdl.org website about that,
but IIRC, SDL employs its own OpenGL API (which may or may not be based on
Mesa3D, I dunno).
