I'm curious about how your library communicates the type of pixel data 
contained in an image. For example, TIFF can hold integral data of various 
sizes, floating point data, or complex data. If a user passes my application 
the path to a TIFF image, how would I determine the type of data contained in 
the image? Am I supposed to use any_image::_dynamic_cast() within a series of 
try/catch blocks?
