 * Image calls
 *
 * These are the calls that front ends should use for manipulating images. You
 * should never call the module functions directly because they may not be
 * implemented (i.e. - the function pointers are NULL). The img_* functions are
 * aware of these issues and will make the appropriate checks as well as
 * marking up return codes with the source.  In addition, some of the img_*
 * calls are high level calls that simply image manipulation
 *
 * Calls that return 'int' that are not explictly noted otherwise return
 * imgtool error codes
