923d926345 st: Remove invalid introspection annotation
(optional) is only valid for (out) or (inout) parameters (that are
marked as such).

However GError** arguments appear as throws="1" in the GIR anyway
instead of an explicit parameter, so we don't need any annotation
at all here.

9168f6055e St Documentation: add and improve documentation for public classes
Much of St is undocumented, aside from input/output arguments. This is
no doubt because a lot of it parallels Gtk closely, but is worth
improving since many new programmers are not familiar with Gtk.

0f947d4ff9 st/theme: Remove entry from files_by_stylesheet after emitting signal
Since e06109c23c we keep old theme nodes
valid during the emission of the "custom-stylesheets-changed" signal.

It turns out that we might still look up the file of a stylesheet using
the files_by_stylesheet hashtable during the emission of that signal,
causing a crash because the assertion in _st_theme_resolve_url() fails.

So fix that and remove the stylesheet entry from the files_by_stylesheet
hashtable after emitting the "custom-stylesheets-changed" signal. And to
be consistent, also remove the entry from the stylesheets_by_file
hashtable after emitting the signal.

e06109c23c st/theme: Unref CRStylesheet after removing old theme nodes
Since we now remove all theme nodes on a stylesheet change (ie.
StTheme's "custom-stylesheets-changed" signal) instead of only
invalidating them, those nodes may not be accessed anymore as soon as
"custom-stylesheets-changed" is emitted.

It turned out though that when comparing them to the newly generated
nodes in `st_widget_recompute_style()` using the
`st_theme_node_paint/geometry_equal()` functions, the properties of the
old nodes will still be accessed, causing a crash since the
CRDeclarations are already freed.

To fix that, keep the reference to the CRStylesheet, which owns the
CRDeclarations used by the theme nodes, around a bit longer, so it's
still possible to access the CRDeclarations inside the
"custom-stylesheets-changed" signal handler. This allows us to compare
the old theme nodes to the new ones since the CSS properties of both are
still valid.

73776508b3 st: Remove broken parsing of @media rules
This code didn't even pay attention to the
cur_stmt->kind.media_rule->media_list, and unconditonally considered
each statement in the ->ruleset to be of kind ruleset.  That seems
broken.

(The theme doesn't use any @media queries, and they are unsupported
anyway.)

28ab1f4af4 Ensure G_PARAM_STATIC_STRINGS for all properties
In `st`, we can do this by using `ST_PARAM_*`. In the other code files,
just use `G_PARAM_STATIC_STRINGS` directly.

This is just a minor convenience to prevent a few unnecessary string
copies.

ffe4eaf00d st: Use G_DECLARE_*_TYPE
Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).

2cf403a3e9 st-theme: Add "custom-stylesheets-changed" signal
StThemeNodes cache matched properties from stylesheets, so when the
list of custom stylesheets changes, the node may miss better matches
(when a stylesheet was added) or have pointers to invalid memory in
the list (when a stylesheet was removed).
In order to allow theme nodes to listen for stylesheet changes, add
an appropriate signal to StTheme.

f7af96dbb2 St: avoid blocking IO to resolve relative urls
realpath() does a series of lstat() on each path component to resolve
symbolic links, but we just want to get an absolute path, and we don't
really care if it is physical or not. Going through a GFile does the
canonicalization we need, and is a lot faster.

5ae2f87ce9 Use pre-split element classes and pseudo-classes to optimize matching
In my testing this cuts the longest time to dispatch(), when showing the
calendar menu for the first time, from 604 to 442 milliseconds,
while reducing additional_selector_matches_style() from 32% to 13% of
CPU time used.

2674d96e54 StTheme: retrive the list of custom stylesheets and use it in loadTheme()
Using the list of stylesheets loaded with st_theme_load_stylesheet(),
one can build an StTheme that is completely identical to the previous
one, except for one property (application-stylesheet).
This allows rt and the user-theme extension to work while respecting
the theming of other extensions.

* Check and update all copyright notices.

* Remove 'Written By:' lines. They are universally incomplete and
  typically indicate only who started a particular file.

a5d4abda00 st-theme: ref items in custom stylesheets list
st-theme stores some loaded stylesheets in a custom
stylesheets list.  When removing items from this list
it unrefs them, but when adding items to the list it
neglects to ref them.  This means that under certain
circumstances the list will contain items that have
already been freed.

4ddc1118bb Work around libcroco < 0.6.2 parsing bug for 'rgba'
To work around a problem where libcroco < 0.6.2 can't handle
functions starting with 'r' or 'u', preconvert 'rgba' to 'RGBA'
when parsing stylesheets and then check for rgba()
case-insensitively.

(libcroco is uniformly case-sensitive, though the CSS spec requires
that ASCII should be handled case-insensitively.)

276d9a9302 Import stylesheet code from hippo-canvas
Import:

  HippoCanvasTheme      => StTheme
  HippoCanvasThemeImage => StThemeImage
  HippoCanvasStyle      => StThemeNode

StThemeContext is a new class managing the theme for a stage and
global properties like resolution.

test-theme.c is a newly written test program to do verification of the
style matching and property handling rules.

Various changes are made in the import:

 - Comprehensive reindentation
 - guint32 pixels replaced with ClutterColor
 - General pseudo-class support added
 - Old-fashioned (non-bordered) background image support added, though
   with no support for repeat, etc.
 - Bug fixes for problems revealed by test program
