README by Mike Gorchak <mike@malva.ua>

OpenGL support was experimentally added in window mode (in
fullscreen mode not yet). If you have QNX RtP v6.1.0 w/ or w/o
Patch A you must download new Photon3D runtime from http://de-
velopers.qnx.com. The versions of OS before 6.1.0 are not sup-
ported.
OpenGL in window mode works well and stable, in fullscreen
mode too, but fullscreen mode has not been heavily tested.
If you have QNX RtP 6.1.0 w/ or w/o Patch A you must download
new Photon3D runtime from http://developers.qnx.com. The versions
of OS before 6.1.0 are not supported.

Problems:
1. Fullscreen mode (in OpenGL mode) has not been written yet.
2. Photon has some errors in detecting how much bits per pi-
xel videomode has.
3. No shared libraries yet. We need manually set flag to
1. While creating OpenGL context artificially selected software
renderer mode (QSSL made acceleration only for Voodoo boards
in fullscreen mode, sorry but I don't have this board, if you
want acceleration - you may remove some line in source).
2. Photon has some errors in detecting how much bits per pixel
videomode has.
3. No shared libraries yet. We need manually set flag to
'configure' --disable-shared.
