mesa: Use floats for viewport bounds.
ARB_viewport_array specifies that DEPTH_RANGE consists of double-
precision parameters (corresponding commit d4dc35987), and a preparatory
commit (6340e609a) added _mesa_get_viewport_xform() which returned
double-precision scale[3] and translate[3] vectors, even though X, Y,
Width, and Height were still floats.
All users of _mesa_get_viewport_xform() immediately convert the double
scale and translation vectors into floats (which were floats originally,
but were converted to doubles in _mesa_get_viewport_xform(), sigh).
i965 at least cannot consume doubles (see SF_CLIP_VIEWPORT). If we want
to pass doubles to hardware, we should have a different function that
does that.
