7ebb9ff6b7 Allow selecting with line-start and line-end bindings
Instead of installing the line-start and line-end key bindings
using the bare ClutterBindingPool API, we can use the internal
clutter_text_add_move_binding(), which automatically installs
the same key binding with the Shift modifier mask.

This allows selecting when pressing Shift+Home or Shift+End.

The selection behaviour is still incorrect around the zeroeth
position, with all the text after the first line being selected.

ea5a6abd9d Add :cursor-size property to ClutterText
We can control the width of the cursor when painting by using
a simple property.

The magic -1 number passed to the setter method will reset the
cursor size to the default one of 2px.

The getter method will return an unsigned integer with the
current size.

ffb500d3a6 Remove unused page up/down key bindings
Moving the text by a "page" depends on being able to define a
"page size" in terms of lines of text. Since we don't define
something similar to an Adjustment that allows us to handle this
behaviour, we should defer the paging implementation to a higher
level class based on ClutterText.

dc49dab350 Fix line start and line end key binding behaviour
Another fix for the key navigation behaviour around the zeroeth
glyph in the layout.

This commit adds a fast path for for the zero index when the
cursor position is set as zero, in case we are using the line-start
or line-end key bindings, similarly to what we did in commit
be64cbcdc2 for the move-up and
move-down bindings.

be64cbcdc2 Fix up/down key navigation
The behaviour of ClutterText around the initial position is still
a little bit erratic.

This commit fixes the key navigation with Up and Down arrows around
the first line of text.

e615b8cc6b Use units in position_to_coords()
We loose precision with a direct conversion for PangoUnits to
pixels, so we should do the conversion as needed, inside the
callers of clutter_text_position_to_coords().

0ac1590378 Lazily create the PangoContext on Text::init
If we create the PangoContext for ClutterText inside the class
initialization we might not have a Clutter main context yet.

Ideally, we should store the Pango context inside the main context
and create it on clutter_init(), but for now we can lazily create
the PangoContext when we initialize a ClutterText instance for the
first time.

786bc4d4d5 Allow only synthetic events with keyval 0
We allow KeyEvents with a key symbol of '0' to fall through only
if they are marked as synthetic. Otherwise we discard them without
mercy.

Synthetic events are useful to test ClutterText behaviour; in fact,
we do use them inside the test suite exactly for that reason.

77b3b9d5f4 Do not use contractions when not needed
I understand we are not Pascal developers, and we don't have to
use cute and cuddly names like "i_am_an_integer_counter", but
a ClutterButtonEvent should be stored inside an "event" variable.
Using "bev" instead? Mmmh, not so much.

2ca7cb46f9 Use the paint opacity when painting a ClutterText
ClutterText should use the paint opacity for both text and
cursor.

ClutterLabel had the wrong behaviour, as it set the actor's
opacity using the text color's alpha channel, and ClutterEntry
completely disregarded the actor's opacity when painting the
cursor.

This commit harmonizes the ClutterText behaviour to always
use a composition of the actor's paint opacity and the text
and cursor alpha channel values, thus behaving more
consistently with the rest of Clutter.

e9c369f86d Add documentation annotations

ClutterText.

f13e00b411 Truncate selections on text insertion
When inserting text on a key press event we should also truncate
the selection.

We should not truncate the selection when inserting any Unicode
character, since changing the selection also changes the cursor
position - and one of the invariants we inherited from ClutterEntry
is that inserting characters programmatically does not change the
cursor position.

35172a7615 Change the binding propagation when truncating a selection
If a selection has been truncated inside a key binding handler,
we should just return and let the usual key event handler continue.

This fixes the case where we deleted a selection using the Delete
or the Backspace keys.

eae98800d2 Use ClutterBindPool inside ClutterText
ClutterText should use the newly added ClutterBindingPool API to
handle key events, instead of its homegrown code.

This commit removes the action/mapping code and defers the entire
key binding matching to a ClutterBindingPool created inside the
Text class initialization function.

b1c366a143 Add Text::get_chars() implementation and tests
The clutter_text_get_chars() function returns a section of the
contents of the Text actor, delimited by a start and an end position.

This commit adds the implementation for that function and a test
unit that guarantees the offset-to-bytes computations are correct.

c72722df8c Add :cursor-color-set property declaration
The :cursor-color-set property is a read-only property that

color set inside the :cursor-color property when painting
the cursor.

We should re-use the offset_to_bytes() implementation from ClutterEntry

d5df1bebcf Add text-visibility accessors for ClutterText
A ClutterText can be put in "password mode" by setting the
text as "invisible": every character inside the Text actor's
contents will be replaced when building the Pango layout with
a specific Unicode character.

The Unicode character is set to '*' by default, but the user
can be changed using the provided API.

fc168a3482 Merge the ClutterLabel properties into ClutterText
ClutterText should have the same properties as ClutterLabel.

While at it, we can finally fix the disconnect between the wrap
and wrap-mode properties and its accessors, that we perpetuated
from GtkLabel.

The ClutterText:line-wrap property and ClutterText:line-wrap-mode
are mapped to the set_line_wrap(), get_line_wrap() and
set_line_wrap_mode(), get_line_wrap_mode() accessor functions
respectively. This should simplify bindings the Vala ones that
map a property into a method.

a98720ae19 Initial import of the Text actor from Tidy
The TidyText actor is meant as a replacement for both ClutterLabel
and ClutterText.

Any text-displaying and editing actor should derive from ClutterText
and implement the various visual cues to differentiate the editable
from the non-editable state. Those visual cues usually belong to
a high-level toolkit, especially if themeing is involved.
