-/**
- * \mainpage The VBO builder module
- *
- * This module hooks into the GL dispatch table and catches all vertex
- * building and drawing commands, such as glVertex3f, glBegin and
- * glDrawArrays. The module stores all incoming vertex data as arrays
- * in GL vertex buffer objects (VBOs), and translates all drawing
- * commands into calls to a driver supplied DrawPrimitives() callback.
- *
- * The module captures both immediate mode and display list drawing,
- * and manages the allocation, reference counting and deallocation of
- * vertex buffer objects itself.
- *
- * The DrawPrimitives() callback can be either implemented by the
- * driver itself or hooked to the tnl module's _tnl_draw_primitives()
- * function for hardware without tnl capablilties or during fallbacks.
