Removed some incorrect comments in the "dc" driver that survived the initial cut-and-paste from the dummy video skeleton.

33 /* Dummy SDL video driver implementation; this is just enough to make an
34 * SDL-based application THINK it's got a working video driver, for
35 * applications that call SDL_Init(SDL_INIT_VIDEO) when they don't need it,
36 * and also for use as a collection of stubs when porting SDL to a new
37 * platform for which you haven't yet written a valid video driver.
38 *
39 * This is also a great way to determine bottlenecks: if you think that SDL
40 * is a performance problem for a given platform, enable this driver, and
41 * then see if your application runs faster without video overhead.
42 *
43 * Initial work by Ryan C. Gordon (icculus@linuxgames.com). A good portion
44 * of this was cut-and-pasted from Stephane Peter's work in the AAlib
45 * SDL video driver. Renamed to "DC" by Sam Lantinga.
