Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication.
...
Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.

image_data_float32 -> image_data_gray32f
NOTE: currently image_data_gray16::pixel_type = std::int16_t (signed 16 bit int) to match GDAL
should we support unsigned types?

Catch and throw PNG exceptions - fixes #1213
...
The png library uses setjmp/longjmp to throw exceptions when reading. If this
is not set up, the png library calls abort(). This change handles the errors
and throws a C++ exception instead.
This issue was found by testing images from pngsuite at
http://www.schaik.com/pngsuite/ . These images are included and a unit test was
added to test both images that should be successful and images that should
throw an exception.
