Hmmm. The only auxillary structures around a Window type in NXLIB
have to do with window properties, see ChProperty.c. However,
these are properly deallocated, and only used if XChangeProperty
is used (please check).
There are two known memory leaks in NXLIB, having to do with
clip regions: XSetClipMask and XSetClipRegion, both in SetClip.c.
Add a printf() to the above functions to see whether these are called
from FLTK. Should this be the case, then I'll have to research
why the regions couldn't be deleted within the NXLIB functions.
I think it has to do with the microwindows GrXXX clip functions
requiring the region to exist after passing to GrSetGCRegion().
The fix here may finally be (without modifying microwindows) to
keep any region allocated for a GC in the local NXLIB GC struct,
and then release it when the GC is deallocated.
Regards,
Greg
