sdl.SetScaleQuality(q$)
q$
argument. The following scale modes are currently supported:
nearest:
linear:
best:
Note that the scale mode is set when a texture (or hardware brush) is created so you need
to call sdl.SetScaleQuality()
before creating a hardware brush/texture. This also means
that you cannot use it for brushes loaded in the preprocessor commands because those will
always be loaded before the script execution starts.
