First shot at new audio data types (int32 and float32). Notable changes: - Converters between types are autogenerated. Instead of making multiple passes over the data with seperate filters for endianess, size, signedness, etc, converting between data types is always one specialized filter. This simplifies SDL_BuildAudioCVT(), which otherwise had a million edge cases with the new types, and makes the actually conversions more CPU cache friendly. Left a stub for adding specific optimized versions of these routines (SSE/MMX/Altivec, assembler, etc) - Autogenerated converters are built by SDL/src/audio/sdlgenaudiocvt.pl. This does not need to be run unless tweaking the code, and thus doesn't need integration into the build system. - Went through all the drivers and tried to weed out all the "Uint16" references that are better specified with the new SDL_AudioFormat typedef. - Cleaned out a bunch of hardcoded bitwise magic numbers and replaced them with new SDL_AUDIO_* macros. - Added initial float32 and int32 support code. Theoretically, existing drivers will push these through converters to get the data they want to feed to the hardware. Still TODO: - Optimize and debug new converters. - Update the CoreAudio backend to accept float32 data directly. - Other backends, too? - SDL_LoadWAV() needs to be updated to support int32 and float32 .wav files (both of which exist and can be generated by 'sox' for testing purposes). - Update the mixer to handle new datatypes. - Optionally update SDL_sound and SDL_mixer, etc.

.SH "NAME"
SDL_EnableUNICODE\- Enable UNICODE translation
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_EnableUNICODE\fP\fR(\fBint enable\fR);
.SH "DESCRIPTION"
.PP
Enables/Disables Unicode keyboard translation\&.
.PP
To obtain the character codes corresponding to received keyboard events, Unicode translation must first be turned on using this function\&. The translation incurs a slight overhead for each keyboard event and is therefore disabled by default\&. For each subsequently received key down event, the \fBunicode\fR member of the \fI\fBSDL_keysym\fR\fR structure will then contain the corresponding character code, or zero for keysyms that do not correspond to any character code\&.
.PP
A value of 1 for \fBenable\fR enables Unicode translation; 0 disables it, and -1 leaves it unchanged (useful for querying the current translation mode)\&.
.PP
Note that only key press events will be translated, not release events\&.
.SH "RETURN VALUE"
.PP
Returns the previous translation mode (\fB0\fR or \fB1\fR)\&.
