[Radiance-general] Create constant radiance image

[John Mardaljevic]

The <return> option of ximage seems to give the maximum radiance in  
any one channel rather than the RGB weighted value, whereas the 'l'  
option gives the expected (RGB weighted) luminance value.  The -ov  
option reports correctly.  Anyone else see this?
