Detailed Description
osg::Program is an application-level abstraction of an OpenGL glProgram. It is an osg::StateAttribute that, when applied, will activate a glProgram for subsequent rendering. osg::Shaders containing the actual shader source code are attached to a Program, which will then manage the compilation, linking, and activation of the GLSL program. osg::Program will automatically manage per-context instancing of the OpenGL glPrograms, if that is necessary for a particular display configuration.

Mark internal glProgram for deletion. Deletion requests are queued until they can be executed in the proper GL context.

Mark our PCSOs as needing relink
static void osg::Program::discardDeletedGlPrograms |
( |
unsigned int |

[static] |
discard all the cached glPrograms which need to be deleted in the OpenGL context related to contextID. Note, unlike flush no OpenGL calls are made, instead the handles are all removed. this call is useful for when an OpenGL context has been destroyed.
