Subject: Re: [PATCH] *CRITICAL* 8bit direct RGB palette not being created
I think that SDL_AllocFormat should create the palette for all 8bit
surfaces. And when the RGBAmasks match the normal 3:3:2:0 we need to
apply the old behavior. If the mask doesn't match that, then we need
to make the right palette assuming the masks are valid (I don't think
we validate any masks for high color surfaces...so we wouldn't here)
Then there's always a palette available for the 8bit surfaces.
This restores the normal behavior and allows for masks to create
palettes automatically for odd masks even, which would be a neato
thing to have in there, as SDL never did this before.

| 10 .PP | |
| 11 \fBSDL_LoadWAV\fP This function loads a WAVE \fBfile\fR into memory\&. | |
| 12 .PP | |
| 13 If this function succeeds, it returns the given \fI\fBSDL_AudioSpec\fP\fR, filled with the audio data format of the wave data, and sets \fBaudio_buf\fR to a \fBmalloc\fP\&'d buffer containing the audio data, and sets \fBaudio_len\fR to the length of that audio buffer, in bytes\&. You need to free the audio buffer with \fI\fBSDL_FreeWAV\fP\fR when you are done with it\&. | |
| 14 .PP | |
| 15 This function returns \fBNULL\fP and sets the SDL error message if the wave file cannot be opened, uses an unknown data format, or is corrupt\&. Currently raw, MS-ADPCM and IMA-ADPCM WAVE files are supported\&. | |
