Date: Mon, 02 May 2005 04:23:16 -0500 From: Jonathan Atkins 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.
