Subject: SDL patch: DGA key events
I kept seeing DGA die on me whenever I press a key.
I tracked it down and it seems that the new indirect X via pointers
system messed it up. It needed to have the pX* pointers well defined to
call, in particular, pXNextEvent. Also, the X11_TranslateKey function
prototype was changed, but not updated in the dga driver. perhaps other
files are also affected.
Not sure what releases may suffer from this too.
thanks!

9 .SH "DESCRIPTION" | |
10 .PP | |
11 Sets the "gamma function" for the display of each color component\&. Gamma controls the brightness/contrast of colors displayed on the screen\&. A gamma value of 1\&.0 is identity (i\&.e\&., no adjustment is made)\&. | |

13 This function adjusts the gamma based on the "gamma function" parameter, you can directly specify lookup tables for gamma adjustment with \fISDL_SetGammaRamp\fR\&. | |
