glPushName - push and pop the name stack
void glPushName(GLuint name);
Specifies a name that will be pushed onto the name stack.
The name stack is used during selection mode to allow sets of rendering commands to be
uniquely identified. It consists of an ordered set of unsigned integers and is initially
glPushName causes name to be pushed onto the name stack. glPopName() pops one name off
the top of the stack.
The maximum name stack depth is implementation-dependent; call GL_MAX_NAME_STACK_DEPTH to
find out the value for a particular implementation. It is an error to push a name onto a
full stack or to pop a name off an empty stack. It is also an error to manipulate the name
stack between the execution of glBegin() and the corresponding execution of glEnd(). In
any of these cases, the error flag is set and no other change is made to GL state.
The name stack is always empty while the render mode is not GL_SELECT. Calls to glPushName
or glPopName() while the render mode is not GL_SELECT are ignored.
GL_STACK_OVERFLOW is generated if glPushName is called while the name stack is full.
GL_STACK_UNDERFLOW is generated if glPopName() is called while the name stack is empty.
GL_INVALID_OPERATION is generated if glPushName or glPopName() is executed between a call
to glBegin() and the corresponding call to glEnd().
