Request: Additional cover art variables

Would like to have:

%_cover_width%
%_cover_height%

Also, since Mp3tag is easily able to find cover files that it would associate with a given audio file, I'd like some means of finding the following

%_cover_size%
%_cover_type%
%_cover_width%
%_cover_height%

for any associated artwork file. Perhaps

%_coverfile% (Maybe True/False or 1/0 instead of a count.)
%_coverfile_size%
%_coverfile_type%
%_coverfile_width%
%_coverfile_height%

and

%_coverfilename%

This would allow one to find files with or without cover art files, and the size of those files. For example, to find covers that are undersized, so that they may be replaced.

The first two

%_cover_width%
and
%_cover_height%

are available since Mp3tag v2.87b:

Since this part of the documentation, also this 3 are available:

%_cover_mimetype% --> Mimetype of first cover art in the tag of the file
%_cover_size% --> Size of first cover art in the tag of the file in bytes
%_cover_type% --> Cover type of first cover art in the tag of the file
