Import SDL 1.2.14 and GLEW 1.5.4.
I am not replacing the following header files used by the Windows build, as I don't have a Windows build setup to test. Please point the Windows build at the header files inside these clean distribution packages and garbage collect the duplicates: GLew/*.h and SDL/Include_1.2. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5711 8ced0084-cf51-0410-be5f-012b33b47a6e

.SH "NAME"
|
||||
SDL_DisplayFormatAlpha \- Convert a surface to the display format
|
||||
.SH "SYNOPSIS"
|
||||
.PP
|
||||
\fB#include "SDL\&.h"
|
||||
.sp
|
||||
\fBSDL_Surface *\fBSDL_DisplayFormatAlpha\fP\fR(\fBSDL_Surface *surface\fR);
|
||||
.SH "DESCRIPTION"
|
||||
.PP
|
||||
This function takes a surface and copies it to a new surface of the pixel format and colors of the video framebuffer plus an alpha channel, suitable for fast blitting onto the display surface\&. It calls \fISDL_ConvertSurface\fR
|
||||
.PP
|
||||
If you want to take advantage of hardware colorkey or alpha blit acceleration, you should set the colorkey and alpha value before calling this function\&.
|
||||
.PP
|
||||
This function can be used to convert a colourkey to an alpha channel, if the \fBSDL_SRCCOLORKEY\fP flag is set on the surface\&. The generated surface will then be transparent (alpha=0) where the pixels match the colourkey, and opaque (alpha=255) elsewhere\&.
|
||||
.SH "RETURN VALUE"
|
||||
.PP
|
||||
If the conversion fails or runs out of memory, it returns \fBNULL\fR

||||
