Daniel Hahler a6718a4a0d Print debug.traceback() with imagebox:set_image, when reading image failed
This made it easier to figure out where a file causing an error was
coming from, but I could imagine that this could become too noisy, and
that there is/should probably be a more streamlined way to enable more
verbose logging / error output.

Uli Schlachter 7967d05915 imagebox: Don't try to scale by infinite (FS#1248)
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.

Uli Schlachter 0ac80ddf30 imagebox: Avoid division by zero
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.

Uli Schlachter b7eb233aee imagebox: Use a different entry for saving the image
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.

Uli Schlachter fa6d996c41 widgets: Add some constructor arguments
This saves space when constructing widgets, because some common cases can now be
done in a single line of code.

Uli Schlachter 90f7f55348 wibox: Make the functions a little more object-y
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.

Gregor Best c2ea920ca0 remove encoding=utf-8 from modelines
This option is no longer valid in modelines, so it has been removed from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

Uli Schlachter 01e6e2a07b imagebox: Refuse invalid images
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.
