I'm getting these errors when compiling Gem on Arch with gcc 6.1.1:

~~~
pix_colorclassify.cpp:156:1: error: narrowing conversion of ‘1.275e+2’ from ‘double’ to ‘unsigned char’ inside { } [-Wnarrowing]
 };
 ^
pix_colorclassify.cpp:170:1: error: narrowing conversion of ‘1.275e+2’ from ‘double’ to ‘unsigned char’ inside { } [-Wnarrowing]
 };
 ^
pix_colorclassify.cpp:184:1: error: narrowing conversion of ‘1.275e+2’ from ‘double’ to ‘unsigned char’ inside { } [-Wnarrowing]
 };
 ^
Makefile:1102: recipe for target 'libPixes_la-pix_colorclassify.lo' failed
~~~

Looks like the latest gcc is a little picky here. :) But maybe `0.5*255` could just be replaced with 127? Suggested patch attached.
