Common gfx plugin spec, version #1.3 maintained by zilmar (zilmar@emulation64.com)
All questions or suggestions should go through the mailing list.

***********************************************************************************
Notes:
------
Setting the approprate bits in the MI_INTR_REG and calling CheckInterrupts which
are both passed to the DLL in InitiateGFX will generate an Interrupt from with in
the plugin.
The Setting of the RSP flags and generating an SP interrupt should not be done in
the plugin
