#1 SetAlpha

[David Snopek]

Need a way to set the alpha value of a surface. May
fall only into TImage. Haven't explored this yet.

Leon Widdershoven:
As to my updated libKSD experience:
a TSurface::SetAlpha( bool _enable, Uint8
surface_alpha_value) would
be nice (SDL_SetAlpha( surface, SDL_SRC_ALPHA,
surface_alpha_value)).
Preferably with a pointer to the SDL documentation of
SDL_SetAlpha since
blitting with surface alpha is not trivial.
