 Hi,

 I know the TGA support is work in progress, but...

 I have some TGA files that have bit 5 set in the "Image Descriptor".  This
 causes ``reader_backend::read_header`` to throw:

     "Unsupported descriptor for targa file"

 The quick-n-dirty fix is just to mask out bit 5 in the check and update
 ``reader::apply`` such that ``read_data`` operates on a
 ``flipped_up_down_view`` if the bit is set.

 Unfortunately I don't have any sample images that I can attach (legal
 reasons), but when I do I will.

 Anyway hope the above is of some use.
