introduce drw_fontset_getwidth_clamp()
getting the width of a string is an O(n) operation, and in many cases users only care about getting the width upto a certain number. instead of calling drw_fontset_getwidth() and *then* clamping the result, this patch introduces drw_fontset_getwidth_clamp() function, similar to strnlen(), which will stop once we reach n. the `invert` parameter was overloaded internally to preserve the API, however library users should be calling drw_fontset_getwidth_clamp() and not depend upon internal behavior of drw_text().
