[paragui-dev] draw::ScaleSurface

[Asko Kauppi]

Going through the API..

ScaleSurface (one of the SDLgfx functions) has three 'faces', two of 
which can be differentiated in C++ but not so in scripting languages:

	ScaleSurface( SDL_Surface*, double zoomx, double zoomy, bool smooth = 
true )
	ScaleSurface( SDL_Surface*, Uint16 newx, Uint16 newy, bool smooth = 
true )

At least in Lua, numbers are just numbers (all double) so I cannot 
really differ between these two. Of course, one could check the 
_values_ of the numbers, but that would be bad: zooming by integers 
wouldn't work!  So I plan to leave the second form out.

Any better alternatives?
