- GS_get_cat_at_xy
- diff gsdrape.c gsdrape.bak - region clipping not working
- (see cont. example in germany location testdata)
- Inconsistent error - depends on view res, maybe check I3d init.
- or num points returned.
- I think fixed now.
- did a bunch of DIFFUSE -> AD changes for trial
- shininess not working
- OK - working now - will be different from SG3d due to infinite light.
- --------------------------------
- NVIZ color bug:
- see /BUGS
- -> small z-scaled elevations are displayed dark.
- - problem in lat/long databases, too

- You are right that there is a problem with normals for surfaces with values
- <0-1>- I have already reported it, it seems that it is also causing parts of
- the surface to disapear for larger values of z for higher resolution/higher
- zscale case. Bill fixed it for the SGI-GL version - if the GL version
- is available it would be good to compare them. I will check with Bill,
- but I would like him to finish the legends first.
- --------------------------------
- The trans.c file should be removed and any calls to the functions in that
- file should be replaced with appropriate OpenGL calls. All the functionality
- in trans.c can be achieved with OpenGL.
- --------------------------------
- This library needs a general overhaul. There are many places which have
- empty functions containing only return statements, as well as several comments
- that say /* You can do better than this */ which indicates areas for
- improvements.
- --------------------------------
- 64-bit support needs to be added and properly handled
