New in version 16.1:
- Disabled internal display scaler which was not properly implemented.
This could cause problems when screen promotion was used.

New in version 16.0b

TinyGL context used in parent powersdl.library thus breaking OpenGL
support if smpeg.library was used.

New in version 16.0
- Updated powersdl.library to SDL 1.2.15 (powersdl.library 16.0)
- Sublibrary revisions bumped
- Fixed endianess bug in SDL headers and libraries

impact on some SDL applications, however it is likely that SDL-UAE no
longer works (no time to check it out)

for SDL display in fullscreen mode (resize is always done in fullscreen
mode atm, this will change to next version again)

trouble for now
- fixed analog joystick code in powersdl.library (caused problems in many
setups)
- fixed powersdl_image.library/IMG_ReadXPMFromArray()
- updated SDK to contain recent startup code, glues and headers
- fixed public SDK to ask for V9 of powersdl_image.library
- changes to SDL_image, SDL_ttf and SDL_gfx were missing from the source
code distribution, updated now (sorry)

New in version 11.13:
- fixed bug where some AltiVec instructions were inlined causing an exception
