41  * stripped down and moved into the SoXt namespace to avoid potential
42  * name-collisions with externally installed GL widgets, and all pure
43  * Xt vs. Xt/Motif ifdef wrappers have been removed (only the Motif
44  * parts remain).  You are encouraged to rather go back to the source,
45  * which you will find with Mesa, than to base your GL widget derivation
46  * on this code.
