Improvements to the cloudsystem:
- A new xml format
- Texture indexing based on the position of the sprite in the cloud
mass, allowing more control over the texture set.
- Improved fog and shading
- Better sprite distribution
- A more natural distribution of clouds, so no more obvious grids.
Switch to defining PU_USE_NONE and providing our own callback
functions to pui for "get window" and "get window size." A new
WindowSystemAdapter class assigns ID numbers to windows for the
purpose of identifying them to plib; the window size can be extracted
from the osg::GraphicsContext class in all the different
implementations (osgViewer, glut, sdl).
Implement a GraphicsContextOperation that runs code in a particular
graphics context, perhaps in another thread, and provides an
isFinished() method to test if the operation has finished. This allows
us to initialize plib PUI properly if there are multiple graphics
contexts without using fgMakeCurrent(). fgMakeCurrent() can't work in
multi-threaded OSG configurations.
Eliminate fgMakeCurrent() and all its uses, either by using
GraphicsContextOperation or by seeing that it is not necessary.
Attach the GUI camera as a slave camera.
Don't manipulate the OSG state in the drawImplementation() functions
for SGHUDAndPanelDrawable and SGPuDrawable; it's not needed.
Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the
preprocessor.
automatically generate config.h-msvc6 with the right version number.
This way Curt will pack the right file because it will be
generated every time he will do 'configure'.
Here are the Boost-less FGEventMgr updates I promised.
Removed Boost dependencies from FGEventMgr.
Removed Boost configure check.
fgMethodCallback now handles const member functions.
I've successfully tested these changes with gcc and msvc.
