gears modules usually don't depend on Awesome C-API. This code has
been placed there for unclear reasons.
Also, there is ongoing work to unify each "concepts" API into one
single page. Having `gears.screen` go against this effort.
This adds gears.screen which contains a wrapper around
screen.connect_signal("added", func) that also calls the callback function for
each screen that already exists. This is added in gears.screen so that it can
also be used from e.g. wibox, if needed. Feel free to move this elsewhere if
that's a bad idea (I'm not really convinced of it).

Instead of using a special _call field on gears.matrix instances which has to be
copied around suitably, this commit changes the code so that the magic is
restricted to a single function in gears.shape.transform. With some metatable
magic, suitable redirection to everything is added.

Wallpapers are usually big images that use up a lot of memory. This commit makes
gears.wallpaper call :finish() on all involved surface to make them free their
memory.
This is a lot faster than waiting for the garbage collector to collect these
surfaces. Due to the large size of wallpapers, such a special case makes sense
for this code.

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.

This library is a wrapper around pcall() / xpcall() that prints an error message
via gears.debug.print_error() in case of errors.

It's unused since commit 0aa4304bda. Before this was a stable sorting
algorithm since table.sort is allowed to be unstable. Apparently we don't need a
stable sorting algorithm anymore.

It is an internal API and is used by `gears.shape`, `gears.pattern`
and `gears.composition` only.
This commit also add `:rotate_at` and `:copy` methods.
This code is imported from Elv13 config and make it very easy
to create shaped objects.
If accepted upstream, other shapes, such as arrow and powerline
will also be added. This commit introsuce the 2 most common
shapes, rounded rectangle and rounded bar.
gears.surface now returns a fallback image surface that is good enough for what
this code tries to do here.

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.

Oh hey, Pango exports an API that allows to query for named colors based on the
famous rgb.txt! Let's use that!

This adds support to gears.color.parse_color to parse things like "#fff" (one
character per color component, without alpha) and "#ffff0000ffff0000" (four
characters per component, with alpha).
This makes sense on its own, but should also help with
https://github.com/awesomeWM/awesome/issues/585.

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.
