When an imagebox was drawn with width or height zero, it tried to calculate the
needed scale factor for making the image fit. Sadly, this would be a division by
zero aka infinite in this case.
Fix this by just not drawing anything if there is no space available.

Given an imagebox i with i.resize_forbidden = false and a valid image set, the
call t:fit(0, 0) would return two times "not a number".
This is because the code first does some calculations to get the input image
into the available space and then tried to do some calculations needed for
scaling images up.
The first calculation already gave us h == 0 == w, the second calculation would
then calculate 0/0. This results in NaNs.
This was only noticed because NaN is not a valid table index in lua.
Fix this by returning 0,0 if we have an image of width or height 0 after the
first calculation. Since 0x0 images are valid in cairo, this also fixes the same
bug with such images.

In 3.4, an imagebox' image is set via "box.image = foo". Since widgets are just
ordinary tables in 3.5, this will actually mess with the imagebox' image without
setting it correctly.
Fix this by renaming the entry to "_image".
A similar patch was applied to the textbox widget ages ago.

This saves space when constructing widgets, because some common cases can now be
done in a single line of code.

This replaces lots of function foo.bar(this, ...) with function foo:bar(...).
There should be no other changes in this commit.
The point is to make it easier for api documentation tools to figure out that
these are methods on objects.

This option is no longer valid in modelines, so it has been removed from
all modelines using the following shellscript:
#!/bin/ksh
git ls-tree -r HEAD | cut -f2 | while read f; do
egrep -e '^(//|--) vim: .*encoding=' $f >/dev/null || continue
sed -E -e '/^(\/\/|--) vim:/s/:encoding=utf-8//' $f > /tmp/foo
mv /tmp/foo $f
done

This makes the imagebox widget refuse images which have a zero or negative width
or height. A zero size causes problems where a division by zero results in inf
which makes various stuff fail in weird ways later on.
Additionally, cairo's "error surfaces" have a negative size. Displaying those
would cause all sorts of weird problems, too, so we better reject those.
