some effort to detect them and output an identity matrix in that case.

a single image and downsamples it.

maps had 0 planes in them rather than 31 empty planes as the spec says they
should.

Added a file that defines a new generic image interface for images in dlib.
...
This is the dlib/image_processing/generic_image.h file. Then I changed all the
image processing functions so that they use this interface. All the changes
are very minor, but there are just a lot of them.
Any user code that was using array2d objects to represent images will still
work. However, this change makes it so that users can use their own custom
image objects with dlib by simply implementing a few global functions for their
image object.

Harmonized the array2d::set_size and matrix::set_size methods.

In particular, array2d::set_size() now simply allows any row and
column sizes so long as they are non-negative.

Changed the serialization code for C-strings so that they don't save the null terminator
...
byte. This makes their serialization format the same as the format for std::string. I had
to revert the previous mod for this because it didn't work in visual studio. This change
fixes that. The code should still be able to read all previously serialized data correctly.
Moreover, any char arrays that aren't null terminated will still be read and written in
their entirety.

Changed the code so that literal strings "i.e. stuff like this" are
...
serialized using the same format as std::string. Previously, the
trailing 0 was also saved so if you deserialized them into a std::string
you ended up with a trailing 0 in the std::string which isn't what you
want.
