This patch fixes various warnings from MSVC.
- Several "truncation from 'double' to 'float'" warnings, easily fixed by
appending 'f' to literals.
- Some "signed/unsigned mismatch" warnings. In read_tag_lutType(), MSVC is
apparently promoting the multiplication of a uint8_t and a uint16_t to an
int32_t, oddly enough. A uint32_t cast fixes the warning.
- |offset| was unused in qcms_data_create_rbg_with_gamma().
- A couple of "overflow in floating-point constant arithmetic" warnings
involving INFINITY in transform_util.c. There is some type confusion here --
in C99 HUGE_VAL is a double and INFINITY is a float. So the HUGE_VAL here
should actualy be HUGE_VALF. But, strangely enough, that isn't enough to
avoid the warning, I don't know why. However, it turns out that any
non-positive value for |interval| will have the same effect, so I just
removed all the INFINITY/HUGE_VAL stuff and used -1 instead.
It also fixes an ARM-only GCC warning.
- "'__force_align_arg_pointer__' attribute directive ignored". This is an
x86-only attribute. Instead of disabling it on x86-64, instead enable it on
i386 (which avoids enabling it uselessly on ARM).
