47461ab59c Fix -Wconversion about float from unsigned int (#84) 
Use of gil::float32_t type members typedefs with variables for half-results.
Observing intermediate values migth be useful during debugging.

ed67f9a571 Replace bitsN[s] aliases with C++11 fixed width integer types 
Import the selection of integer types into boost::gil namespace,
  and move from channel.hpp to typedefs.hpp for easier access.
Replace bits32f with float32_t and bits64f with float64_t
  - kept as alias of scoped_channel_value.
Move float64_t (bits64f) to typedefs.hpp.
Replace the four {float|double}_{zero|one} min/max channel values
  with float_point_zero and float_point_one templates.
Replace <boost/cstdint,hpp> with C++11 <cstdint>.

Introduce preference of using declaration instead of typedef.
Reformat typedefs.hpp to take advantage of the using declaration
  - works much better for left-to-right reading, alias name as
    most important detail comes first.
Add some of missing #include typedefs.hpp, sort some headers.

f3fd792787 Test float-point divisor for less/greater-than Zero 
Add divisor check to point2<T>::operator/=, if Zero do nothing.

This hack helps to avoid compiler warnings without
polluting the source with pragmas.

056415f513 Improve casts in channel_convert_from_unsigned (refines PR #74) (#76) 
Add cast to explicitly indicate val promotion to at least
32-bit integer. The arithmetic operations are performed on
int of higher rank type. Finally, since the result value is
guaranteed to fit range of 8/16-bit result integer type,
it is safe to cast.
This should make it clearer for a reader that subtleties
of implicit promotions and conversions have been considered.

0984b7586b Fix some warnings reported by clang (#74) 
- unused parameter
- shadowed typedef
- implicit conversion changes signedness:
  int to signed <int>
  int to unsigned <int>

Note, arithmetic op is performed on int as higher rank type
with result is in range of return type, safe to cast.
