A request for future gdk_scale_pixbuf...

["Lewin A.R.W. Edwards" <larwe larwe com>]

The current function doesn't operate very intuitively, and it's 
ambiguous as to what exactly happens to the source pixbuf.

What I mean by this is that :

a) the idea of scaling by separate x,y scale factors and translating the 
image isn't exactly what I'm used to from other OSs, plus it introduces 
floating-point inaccuracy worries.

and

b) the API documentation, as written, implies that the function actually 
reallocates the source pixbuf and changes the pixels inside it. I am 
guessing that it really just reads the source pixbuf line by line and 
performs an implicit transformation before blitting the result to the 
destination pixbuf, but that's not what the documentation says :)

I was hoping that it worked like the drawing code in (say) OS/2, where 
you specify a source rect within the source bitmap and a destination 
rect within the destination bitmap. That way, everything is always an 
integer.

I guess it's possible to wrap the function to get the behavior I desire, 
but I'm still working with trying to understand how it works :/
