[Pkg-fonts-devel] Bug#700933: Unchecked conversion of input to enum

While building the package using our research compiler infrastructure, which
also performs more strict type checking, we noticed the following problem that
possibly triggers undefined behaviour:
In fontforge/scripting.c, the function bExpandStroke stores user input values
(of type double) in a field of type enum linecap (first appears in line 4653,
but also occurs multiple other times).
As there is no sanitization of input in place, the assignment may result in
arbitrary values being set.
