Subject: [Patch]: Improved menu code for SDLMain.m
the attached patch improves the menu setup for SDL apps built without a
.nib file. On 10.3, the application menus are empty with the current
SDL CVS version; after this patch, a proper app & window menu, with
"About", "Hide", "Quit", "Minimize" etc. entries are visible, just like
with the .nib enabled applications.
This *should* work on 10.2 and even 10.1, but I can't guarantee it, so
somebody should test there, ideally.
I also changed the way setupWorkingDirectory works by making use of the
Bundle APIs, that results in (IMO) less hackish code.
Finally, I added some "static" keywords to ensure that certain local
functions are not exported (that's just a paranoia change, I guess:
never pollute linker namespaces if you can avoid it).

Each table is an array of 256 Uint16 values, representing a mapping between the input and output for that channel\&. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision\&. You may pass NULL to any of the channels to leave them unchanged\&. .PP This function adjusts the gamma based on lookup tables, you can also have the gamma calculated based on a "gamma function" parameter with \fISDL_SetGamma\fR\&. .PP Not all display hardware is able to change gamma\&. .SH "RETURN VALUE" .PP Returns -1 on error (or if gamma adjustment is not supported)\&. .SH "SEE ALSO" .PP \fISDL_SetGamma\fR \fISDL_GetGammaRamp\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:01
