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().
