A GraphicsStateGuardian for rendering into DirectX9 contexts.
The ShaderContext is meant to contain the compiled version of a shader string.

static void init_type()
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Definition: typedObject.cxx:44
This class gives the ability for a user-friendly way of creating a vertex declaration for DirectX 9.
This is our own Panda specialization on the default STL vector.
