Note that MGL is _not_ an OpenGL library, though! It's a 2d graphics
lib written by SciTech, that includes a copy of MESA, which is a
free OpenGL implementation written by some other people. No problem
there, except for the fact that SciTech failed to explain this in
any of their documentation, which has confused a lot of people who
don't realise that they can get the exact same OpenGL code directly
from the MESA site. This is particularly bad because MESA is
distributed under the LGPL, while the SciTech MGL code uses their
own license that is far more friendly to commercial use. By not
making this properly clear, SciTech have created a situation where
a lot of people are likely to be inadvertently violating the LGPL
because they don't realise it applies to this code.

So beware. MESA and MGL are both good products, but it is important
that you understand which is which, and don't confuse the two.
