Previously, odd things could happen if a widget was getting fitted into a
negative width or, even worse, width being NaN (not a number)!
This can e.g. happen due to a margin layout which doesn't get enough space to
even draw the margin that it is supposed to add.
Fix this by enforcing a minimum value of 0 for the width and height that a
widget gets fitted into.

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.

There is a strong hint that you are doing something wrong: You call
client.emit_signal(some_signal, c). Chances are high that this signal is
supposed to be emitted on the client object 'c' instead of the underlying client
class.
This applies to awful.rules' usage of this signal.

Before commit 1b2826 in lgi, the get_rgba() function on cairo SolidPatterns was
specified like this:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The above commit fixed this (without saying so) and the code became:
get_rgba = { ret = cairo.Status,
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' },
{ ti.double, dir = 'out' } },
The prototype for the corresponding cairo function is:
cairo_public cairo_status_t
cairo_pattern_get_rgba (cairo_pattern_t *pattern,
double *red, double *green,
double *blue, double *alpha);
As you see, this functions gets four double* as arguments and it will save its
result via those pointers. Old versions of lgi call this function with too few
arguments and this will cause a segmentation fault when cairo dereferences an
invalid pointer.

If a client gets moved to a screen without any selected tags, that client
disappears and it is non-trivial to get it back. Since this is unexpected and

This allows to apply properties and callbacks to a client like
awful.rules.apply would do, without the matching part.
This is useful with the new startup notifications, and lets you apply
the same properties and callbacks from e.g. a manage signal handler.
If a drawable has an opaque background, we don't need pseudo transparency and
thus its content don't change when it is moved. However, when we need pseudo
transparency, then we have to redraw the drawable to apply the new background.
Previously we just always did the redraw. This commit adds a helper function
gears.color.create_opaque_pattern() that analyzes a cairo pattern for
transparency. We use this new function to only redraw-on-move when there is
actual pseudo transparency in effect. Otherwise, this redraw can be skipped.

This allow to spawn something, then apply some properties or rules when
the client show up ("manage").
This commit add:
* "startup_id" property for all clients object (immutable, can be nil)
* Second return value to awful.util.spawn() with the startup_id
* Update the documentation
Example:
local wait_for_it = {}
local pid,snid = awful.util.spawn("urxvtc")
wait_for_it[snid] = {ontop=true,sticky=false,
tag = awful.tag.gettags(mouse.screen)[1] }
client.connect_signal("manage", function (c, startup)
if c.startup_id and wait_for_it[c.startup_id] then
for k,v in pairs(wait_for_it[c.startup_id]) do
c[k] = v
end
if wait_for_it[c.startup_id].tag then
c:tags({wait_for_it[c.startup_id].tag})
end
end
end)

Added set_expand function with options of "none" "outside" or "inside" modes.
The "inside" mode is the default and will result in the original behavior. The
main benefit is being able to actually center a widget in the available space
with options of how to draw the outside widgets (expand to take the space,
or not.) Further functionality can be had by ommiting one of the outside
widgets. Set default layout mode in the constructor.

Pressing CTRL+DELETE removes the visible history entry, if any, then moves to the next history entry (like pressing DOWN would do).
If the last history entry is removed the previous one is shown in the prompt (like pressing UP would do).
CTRL+DELETE works on history entries only: i.e. it has no effect on a command entered but not executed yet.
To implement above behaviour I added saving history table to file on Escape key press.

This commits adds awesome.register_xproperty(). This allows lua code to register
arbitrary X11 properties with awesome which will then watch these properties.

This reverts commit 20afb26080.
The commit caused endless loops with tracebacks like this (shortened):
lib/awful/ewmh.lua.in:122: in function <lib/awful/ewmh.lua.in:117>

When a client's geometry changes (and I consider the border width to be part of
the geometry here) and that client is one of fullscreen or
maximized_{horizontally,vertically}, make sure that the geometry as specified by
the state is still obeyed.
This also (accidentally) fixes things when a client gets moved to another
screen!

When we receive a _NET_ACTIVE_WINDOW request on the root window, we used to just
focus and raise the window. This didn't do much for clients which are on
non-selected tags.
Thus, this commit makes awesome emit request::activate on the client instead.
This is used in awful.ewmh to implement the old behavior again, but with
additionally marking the client as urgent if it isn't visible.
People who don't like this behavior can use client.disconnect_signal to disable
this behavior again. To make this really possible, awful.ewmh becomes a
"non-nil" module.

When an area is split in two, for example horizontally, one of the windows
should have height math.floor(previous height / 2) and the other
math.ceil(previous height / 2), to be certain that no gaps are left between the
windows.
For instance, if the first window has height h and the second window has height
math.floor(h / 2), the height of the third window should be math.ceil(h / 2)
instead of the same as for the second window.
So to compute the size of window n + 1 it’s necessary to remember the size of
window n - 1 as well as that of window n.

This is used in the C code to keep tags alive even when nothing else refers to

When awesome restarts because a new screen was added or removed, clients can end
up being on a different screen than before the restart. However, the tags will
be carried across the restart. This means that a client could end up being
tagged with a tag from another screen. This results in weird behavior of tag
switches and confuses users.
To work around this, remove the client from any tags that are on a different
screen during startup. If the client ends up without any tags, it will then be
tagged with the currently selected tags.
