The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
This now does directly what previously awesome.load_image() did. Also,
this commit removes the only caller of awesome.load_image(), so that
function could (in theory) be removed now.

This function draws the wanted shape to a cairo image surface and then
uses it to set the shape of the passed-in object. After this commit,
this temporary image is finished afterwards, making it free most of its
memory immediately instead of only later when the garbage collector
collects the image surface.

Previously, the lgi check used the normal Lua interpreter to check if
lgi is installed. However, nothing ensures/requires that awesome is
built against the same Lua version as the Lua interpreter. This means
that if lgi is only available for some Lua version, then the check could
succeed even though awesome would later fail to start. Also, the check
might have failed even though awesome would not have any problems
finding lgi.
This commit replaces lgi-check.sh by a small C program which does the
same thing. This ensures that the same Lua version is used as awesome
will be using.
There are some places that still use the Lua interpreter: Example tests
(run through the Lua interpreter directly) and unit tests (run through
busted). For unit tests, this should not make much of a difference and
example tests might later get similar treatment.

This marks the functions gears.surface.widget_to_svg() and
gears.surface.widget_to_surface() as deprecated in awesome 5. This means
that by the time that awesome 6 becomes a thing, we can finally remove
these...

For some reason, the code here tried to handle widget::redraw_needed
signals even though it should apparently/obviously only produce a
current snapshot of the widget's look.
Fix this by just removing the redraw code.
While here, also factor out the widget context table into a local
variable and re-use it for the initial layout and for the later draw.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

Loading a file normally has the same behaviour as before. First the cache is
checked and if nothing is found, the file is loaded and cached.
This commit changes the behaviour of loading a file uncached. This no longer
removes the file from the cache if it is cached (why should it?) and also does
not put it in the cache.
This means that users of load_uncached and load_uncached_silently can now freely
modify the resulting surface without interfering with other API users.

Before this, calling one of the loading functions with a nil argument always
made it return the default 0x0 surface. With this change, the passed-in default
value is now properly applied.

Previously, a Lua error was thrown when loading a file failed. Most callers are
not prepared for this and the result is less than optimal.
This commit makes the functions print the errors and return nil instead. For
callers that want to handle errors themselves, "_silent" variants of the
functions are introduced which just return errors to the caller.
