[osg-submissions] FLT export: minor fixes

[Robert Osfield]

Thanks changes merged and submitted to SVN.

I have a model here that produces some errors, unfortunately it's not
my to redistribute.


osgconv umemain_new.flt test.ive
Can't find texture (3) sp_skylt.inta
Data written to 'test.ive'.

(normal warning nothing wrong yet)

Then converting back to .flt :

osgconv test.ive test.flt
fltexp: GL_POINTS not supported in FLT export.
fltexp: GL_POINTS not supported in FLT export.
fltexp: GL_POINTS not supported in FLT export.
fltexp: GL_POINTS not supported in FLT export.
Data written to 'test.flt'.

Then viewing it:

osgviewer test.flt

The model is viewable but object in are positioned wrong.

Then if I convert from .flt to .flt directly I get a seg fault.

osgconv umemain_new.flt test.flt
Can't find texture (3) sp_skylt.inta
Segmentation fault (core dumped)

I don't have a debug build yet though so can't provide line numbers.
