f60a469a34 st/scroll-view: Make fade effect take ClutterMargin
Instead of taking just vertical/horizontal offsets, take a ClutterMargin
to allow us set the fade offsets on each direction specifically. Also,
handle negative values in margins, the fade effect will run in the negative
space left by the scrollview padding instead. Another difference now is
that areas outside the extents of the effect will be transparent, instead
of the effect ending abruptly past the given extents.

This will be used by the app grid, in order to selectively let see either
of next/prev pages while navigating.

While at it, fix code style issues in st_scroll_view_update_fade_effect(),
and clean up unused variables from the GLSL code.

a977c1388a st: Add StPolicyType enum
In order to replace GTK+'s GtkPolicyType. It's bit-compatible with it, too.
All callers have been updated to use it.

This is a purely accessory change in terms of X11 Display usage cleanup,
but helps see better what is left.

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).

6fb044f351 st: Make st_scroll_view_update_fade_effect() public
Using fixed fade offsets is not always appropriate, this will allow
to set them from code instead.

1bd8c67041 st-scroll-view: Add :overlay-scrollbars property
If enabled, scrollbars take away from the allocation given to the
view's content. This is usually preferrable to painting the bars on
top of the content, but there are exceptions, for instance when the
content needs to be centered with regard to the view as a whole.
Add a :overlay-scrollbars property to account for those cases.

e7289378b7 st-scroll-view: Make the fade effect and offset themable
Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of
0 disables the effect.

This new CSS approach replaces the current programmatic toggle of
the 'vfade' property. A new CSS style class name 'vfade' is used as
a replacement for the old property.

ce72aaf008 Fix up copyright and license notices for St
* Make sure all source files have a LGPL copyright header, and standardize
  non-standard variations of the header to a common form.

* Check and update all copyright notices.

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

fc39919856 Add top and bottom shadows to app browser
Add a 'vshadow' property to StScrollView, which, when turned on,
overlays gradient shadows on the top and bottom of the StScrollView.

Turn this on for the StScrollView used for the app browser.

18c5405b79 [StScrollView] Add support for GtkPolicyType for scrollbars
Previously we were hacking out the vertical scrollbar, this patch
allow us to sanely say in which directions we want to scroll.

Note this patch intentionally changes St to depend on GTK+ in the
API.  I believe this is a correct long term change where we should
view St as co-evolving with GTK+ rather than replacing or paralleling.

e91e8e993d Add emacs mode-lines to ST sources
To each .c and .h file, add:

 /* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */

'gnu' is the default anyways for Emacs, but indent-tabs-mode is not,
so this sets things up to correspond to the policy of no-tabs.

83402957bb Add GObject Introspection annotations
Add GObject Introspection annotations to methods where needed, in
particular adding (transfer none) to return values that don't transfer
ownership.

st_texture_cache_get_actor() and st_texture_cache_get_texture()
are annotated as (transfer none) since they return a newly
created *floating* texture.
