[PD-dev] [GEM] cvs checkins

[Daniel Heckenberg]

I've made a couple of changes to GEM CVS:

(all) added "render" message to [gemwin]  to force a single frame rendering
right away
(all) allowed "frame 0" to [gemwin] to set the automatic frame rate to 0
(win only) added "topmost" message to make gem window stay on top
(win only) added VC++7 workspace and project
(win only) fixed pix_film initial frame crash and changed pix_film to be
more robust

ToDo:
incorporate pix_filmNT changes into the pix_filmNEW object (filmAVI).

Things to discuss:
-It would be very handy to be able to share uploaded textures across gem
lists in a similar way to the pix sharing mechanism.  This should be easy to
implement.
- I'm going to implement some control over window clearing into gemwin.
This can be used to do multipass rendering and various other things.  I'm
proposing a couple of changes:
- "clearmode f" message to [gemwin] to set which buffers are cleared
automatically in each render cycle
- [clear] object to be inserted into the rendering chain to force a clear at
that time.

It could be argued that a "clearnow" message to the [gemwin] would be more
appropriate since the clearmessage forces a global change.  What do you
think?
