Get rid of legacy glTexParameterf calls.

ES 1.0 didn't have glTexParameteri, which is why we sometimes used
glTexParameterf. However, we shouldn't use glTexParameterf because
that's treating integer values as floating point, which is not type
safe. ES 1.1+ and ES 2.x have glTexParameteri, and we don't really care
about supporting ES 1.0 in any case in Qt 5.
