for generated brushes. The maximum radius we allowed for generated brushes was not used consistently everywhere. In the API call we clamped it to 0.0-32767.0, while the param_spec set min and max to 0.1 and 4000.0, and the brush editor used a maximum of 1000.0. Using a large value (probably anything larger than 4000) would sooner or later lead to a crash. Instead of manual changes everywhere, let's define a maximum and minimum in one place and use that wherever we need the min/max values. Use the values as set in the param_spec for the defines. The only place we can't easily do that is in brush.pdb, so we add a comment above our defines that the values need updating there too. Actually we should probably use more defines for other values too, that way there is less chance of min/max values getting out of synch throughout our code.
