please see below for changelog entry and diff prepared against
yesterday's cvs update for the first step in the "best possible
variable-width fonts support" changes.

i used /* iftc */ to mark casts used to maintain the "iso-functional
type contour", to distinguish them from other casts that may be around.

any suggestions on how to improve this would be greatly appreciated.

        indent.c (last_known_column): Now a float.
        (current_column_1, position_indentation, current_column,
        string_display_width): Return float.
        (Fcurrent_column): Cast `current_column' return value to int.
        (Fcurrent_indentation): Cast `position_indentation' retval to int.
        (indented_beyond_p): Third arg now a float.
        (compute_motion, vmotion): Cast `indented_beyond_p' 3rd arg to float.

        lisp.h: Update `current_column' and `indented_beyond_p' signatures.

        bytecode.c, cmds.c, keymap.c, minibuf.c, xdisp.c:
        Cast `current_column' return value to int.

        xdisp.c: Cast `indented_beyond_p' 3rd arg to float.

It seems reasonable; if you see that it works, how about installing it?

ok.  fyi, i see that it works by temporarily adding `float-current-column'
that exposes the float and running a scan on some files (code below) w/o
error.

further testing raises another question.  inserting text increments the
column normally, but this is not the case for images (on the same line)
which add 1 to the column only:

      TEXT-IMAGE-TEXT2
      012345    6789...

i surmise there is no code that depends on TEXT2 column, or that such code
would silently break depending on how we fix this underspecification, but
that it's not really a big deal, just something to mention to programmers
(and specify more precisely, of course).  am i missing something?  does
anyone else see different behavior?

      inserting text increments the
    column normally, but this is not the case for images (on the same line)
    which add 1 to the column only:

This is because the image is placed on top of one character.
The indentation code only knows that it is one character.
It pays no attention to the image on it.

When the indentation code knows about widths of characters, then it
should also check for images and use the width of the image
to do its calculation.

I think that if you use the `iterator' facility
it will automatically handle that properly.

It's possible that indent.c should look at the glyph matrices, where this 
information is already spelled out.  (From past discussions, indent.c 
cannot be bases _solely_ on glyph matrices, since sometimes indent 
functions are invoked for portions of the buffer which are not displayed; 
but if the relevant text _is_ displayed, going by the glyph matrix might 
prove much simpler.)

    information is already spelled out.

I don't think there is any way to determine reliably whether
part of the glyph matrices correspond correctly to the buffer.
So you could only do this when redisplay is up-to-date for the buffer.
At that point, you know the glyph matrices do match the buffer text.

I tend to think it is not worth the trouble of writing special code to
handle that particular case.
