Subject: GRX vs VOGL

Just in case I am reinventing the wheel here, I thought I might see
if anyone has already adapted the VOGL 'GL' graphics clone for LIBGRX
graphics --- I have a very rough driver half-written (if anyone is
interested in a jump-start) but a full driver would save a lot of
legwork.

Also, I am looking into adapting the LIBGRX event system to accomodate
the 3D "FastTrap" pointer made by MicroSpeed.  Being 3D, this needs to
add to the existing event system to accomodate the place, count, scale
and reset of the Z dimension, but otherwise, the only difference between
this device and a mouse is the function calls are up in the INT 76 range.
Any advice or suggestions on how to insert a new event type?

One last quick question that received no replies last time (it may not have
made the list) --- in Borland C++ it is considered 'bad' to mix malloc and
new, and while I expect malloc'ed memory will require 'free' and not
'delete' to discard it, there seems no obstacle to mixing malloc in the
C code with new/delete in the C++ side.  Is this true?

One very last question:  The LIBGRX manual has functions for getting the
BIOS font, but there doesn't seem to be a way to get the font options
record for that font --- VOGL requests both the 8x8 and 8x14 fonts for
emergency messages and the @:8x8.fnt (or whatever) call seems a very
expedient way to get this, but once I have the font loaded, how do I
use it?  A short code example would be most useful.
