/* Dummy SDL video driver implementation; this is just enough to make an
* SDL-based application THINK it's got a working video driver, for
* applications that call SDL_Init(SDL_INIT_VIDEO) when they don't need it,
* and also for use as a collection of stubs when porting SDL to a new
* platform for which you haven't yet written a valid video driver.
*
* This is also a great way to determine bottlenecks: if you think that SDL
* is a performance problem for a given platform, enable this driver, and
* then see if your application runs faster without video overhead.
*
* Initial work by Ryan C. Gordon (icculus@icculus.org). A good portion
* of this was cut-and-pasted from Stephane Peter's work in the AAlib
* SDL video driver. Renamed to "DUMMY" by Sam Lantinga.
