Detailed Description

push and pop GL states on constructor/destructor 

Helper class pop(save) OpenGL states on construction and push them on destruction automatically.

Using matching push/pop pairs is easy with this class. Sample usage:

// begin var. scop
{
// save state by push
StatekeeperGL myTmp;   
// change the state, fire GL calls 
...   
// reload state by destructors pop call automatically
}
// end var. scope

There should not be a performance impact if you use display lists.
