#2211: Can not create image of Regular type

Milestone:  Boost 1.36.0          |   Component:  GIL    
  Version:  Boost 1.36.0          |    Severity:  Problem
 Keywords:                        |  
----------------------------------+-----------------------------------------
 The GIL docs say images, views, and locator's can be created from any type
 that satisfies the GIL concept 'Regular'

 quoted from boost/gil/image.hpp:
 {{{
 #!cpp
 /// Note that its element type does not have to be a pixel. \p image can
 be instantiated with any Regular element,
 /// in which case it models the weaker RandomAccess2DImageConcept and does
 not model PixelBasedConcept
 }}}

 Unfortunately this does not seem to be true, even the simple test attached
 fails to compile.

 Depending upon whether I define the image to be planar or not, I get
 errors with different metafunctions:

 for IsPlanar == true:
      the error is in the view_type_pixel metafunction, which invokes
 channel_type.
 if IsPlanar == false:
     the error is in the is_planar metafunction.
