- * (G)eneric Mesa interface
- *
- * This generic interface to Mesa provides minimal functionality. It's
- * intended to be an _experimental_ interface for projects such as Linux/3-D
- * hardware. There may eventually be many different implementations of this
- * interface for different operating systems and graphics cards.
- *
- *
- * Usage:
- * 1. #include <GL/gmesa.h>
- * 2. use GMesaCreateContext() to get a new GMesa context
- * 3. use GMesaMakeCurrent() to activate a GMesa context
- * 4. do your OpenGL rendering
- * 5. use GMesaSwapBuffers() in double buffer mode to swap color buffers
- * 6. use GMesaDestroyContext() to destroy a GMesa context
- * 7. use GMesaGetContext() to return the current context
- *
- *
- * Implementation:
- * 1. GMesaCreateContext() should initialize the hardware and return
- * a GMesa context struct pointer
- * 2. GMesaMakeCurrent() should activate the context
- * 3. GMesaDestroyContext() should free the context's resources and
- * reset the hardware
- * 4. GMesaSwapBuffers() should swap the front/back color buffers for
- * the current context
- * 5. It may be the case that an implementation of this interface only
- * supports one context at a time. That's fine.
