time for a new release?

[James W. W. <os...@jw...>]

I propose that we build a new release of Quesa.  Should it be version  
1.9 or 2.0?

Here's a draft list of changes.  Additions or corrections are welcome.

* New OpenGL renderer supporting stencil shadows, more than 8 lights,  
emissive color attributes, and per-pixel lighting.  It uses vertex  
buffer objects (VBOs), display lists, and triangle strips for speed  
optimization.
* New plug-in for 3DS file format.
* New hidden line renderer.
* Added support for hardware-accelerated pixmap draw contexts using  
framebuffer objects (FBOs).
* New draw context options to sync drawing to refresh or put the  
drawing surface behind the window.
* New HIQuesaView sample project illustrating use of Quesa in a Carbon  
custom view.
* A single Mac framework that can support both Carbon and Cocoa  
contexts.
* Improved support for partial ellipsoids and tori.
* New renderer option to indicate whether textures should be assumed  
to have premultiplied alpha.
* Implemented group culling.
* Removed obsolete draw region functions.
* Added FSRef-based storage objects on the Mac.
* Added some utility algorithm sources.
