81541e6940 [docs] Parameter naming fixes
The name of the parameter in the header and the one in the gtk-doc
annotation on top of a function must match.

Unfortunately, there is an index() function declared inside strings.h
which makes gcc complain for the "index" argument as soon as we
enable the extra compiler flags we use when distchecking.

Hence, we need to rename "index" to "index_" in the header and in
the source files.

64de0411ea [cairo-texture] Remove the construct only restriction on surface size
It is possible to change the surface size after construction with
clutter_cairo_texture_set_surface_size so it doesn't seem right to
restrict changing the properties.

clutter_cairo_texture_resize_surface_internal is called in a handler
for the notify signal. It is called there rather than directly in the
set_property handler so that changing both properties in a single
g_object_set will only cause one resize. The constructed override is
no longer needed.

resize_surface_internal will now bail out if the size of the surface
is already the right size.

cf5d69139d [texture] Do not mix fixed point and units values
Like we did for ClutterActor in commit cdb78ec4, fix ClutterTexture
usage of CoglFixed and ClutterUnit values without conversion between
the two types.

cdb78ec4d2 [units] Do not use fixed point and units interchangeably
Clutter units are, at the moment, implemented as a value in fixed point
notation using the same format as CoglFixed. This is, though, an
implementation detail. For this reason, units should not be treated as
CoglFixed values and should be converted to and from fixed point using
the provided macros.

This commit updates the usage of units and fixed point values in
ClutterActor and rationalises some of the transformation code that
heavily relied on the equivalency between them.

5e0daa8ecd Improves tfp performance on Nvidia
Some drivers (e.g. Nvidia) get upset if you try to create multiple glx pixmaps
for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.

4168ed09de Fix calculation in clutter_cubic_bezier
The calculation for cubic bezier curves had an extra multiplication by
3 which was causing the curve to go over 1.0 very quickly. This had
the affect of making test-animation appear to complete much before the
completed signal is emitted.

2bf815131a [clutter-interval] Fix calculation of interval for unsigned types
The patch makes it cast to double before subtracting the original
value from the target value. Otherwise if the target value is less
than the original value then the subtraction will overflow and the
factor will be multiplied by a very large number instead of the
desired interval.

The problem is demonstrable using the border-width property of
ClutterRectangle.

e130e0c9b3 [cairo-texture] Silently discard 0x0 surfaces
The current CairoTexture can be created with a surface size of 0
by 0 pixels, but a warning will be printed.

Worse, the surface can be resized to be 0 by 0 pixels without a
warning. The :surface-width and :surface-height properties accept
a minimum value of 0, and not check is performed on either the
constructor or set_surface_size() parameters to enforce the "greater
than zero" rule.

The correct and consistent behaviour is to allow a 0 by 0 pixels
surface size everywhere; inside surface_resize_internal(), the
current surface will be destroyed and if either :surface-width or
:surface-height are set to 0, the resizing terminates.

Attempting to create a Cairo context from a CairoTexture with
either :surface-width or :surface-height set to 0 will result in
a warning.

This allows:

  - creating a CairoTexture with :surface-width or :surface-height
    set to zero and delaying the surface resize at a later point;
  - resizing the surface to 0 by 0 pixels to destroy the image
    surface used internally;
  - increase the consistency in the usage of CairoTexture.

ff92cc9766 Convert clutter_path_get_position to take a gdouble instead of an alpha value
The gdouble value represents an interval along the path from 0.0 to
1.0. This makes more sense than using an alpha value because paths are
not directly related to ClutterAlphas and the rest of the Clutter API
tends to expose gdouble arguments.

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.

ffb500d3a6 Remove unused page up/down key bindings
Moving the text by a "page" depends on being able to define a

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.

cf9dea7cf6 Print a warning when creating a cairo_t while painting
If you create a Cairo context in the middle of a paint run and then
you destroy it, the CairoTexture will have to upload the contents of
the image surface to the GL pipeline. This usually leads to slow
downs and general performance degradation.

ClutterCairoTexture will warn to the console if Clutter has been
compiled with the debug messages and if create() or create_region()
are called while an actor is in the middle of a paint.

3f2c9fe6b3 Set the IN_PAINT private flag
When calling clutter_actor_paint() we should be setting the
CLUTTER_ACTOR_IN_PAINT private flag. This allows signalling
to each Actor subclass that we are effectively in the middle
of a paint sequence. Actor subclasses can check for this
private flag and act based on its presence - for instance to
avoid recursion, or to detect performance degradation cases.

e934ad03ca Add ClutterCairoTexture
Move the ClutterCairo actor from a separate library to an in-tree

ClutterCairoTexture is a simple texture subclass that allows you

contents to be uploaded to a GL texture.

The image surface used is not hardware accelerated.

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.

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

is that inserting characters programmatically does not change the
cursor position.

4d62da80ad Coalesce ClutterLabel API usage
ClutterText replaces ClutterLabel, so it should expose the same
kind of API - ideally with the minimal amount of changes, so that
the porting is trivial.

a91bb5450f Group all the integer private fields
Integer fields using the ": <bits>" notation should be packed
together so that the compiler can optimize the structure size
correctly.

f9bf187e5d Use internal headers
Since ClutterText is part of Clutter, it can use the internal
and private headers instead of the catch-all clutter.h.

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.

bc6a107ff6 Do not modify parameters in place
When the apply_transform_to_point() and its relative variant
landed in Clutter 0.3, the initial approach was to modify the
passed vertex as an in-out parameter. This was later dropped
in favour of a more consistent out parameter.

Unfortunately, the implementation never changed: both methods
where modifying the passed vertex with the partial results of
the computations.

This commit copies the contents of the "point" ClutterVertex
argument inside a stack variable and, for good measure, constifies
the argument.

Thanks to Thomas Steinacher for catching this in Python.

9537f8e4ae Use a single index array
There's no point in clearing the index array because it is always the
same sequence of indices regardless of the vertices. Instead it is
just added to when there are more vertices than ever before.

	* clutter/cogl/gl/cogl-primitives.c:
	* clutter/cogl/gles/cogl-primitives.c: Changed the semantics of
	cogl_path_move_to. Previously this always started a new path but
	now it instead starts a new disjoint sub path. The path isn't
	cleared until you call either cogl_path_stroke, cogl_path_fill or
	cogl_path_new. There are also cogl_path_stroke_preserve and
	cogl_path_fill_preserve functions.

	* clutter/cogl/common/cogl-clip-stack.c:
	* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
	stack code quite a bit to make it more maintainable.  Previously
	whenever you added a new clip it would go through a separate route
	to immediately intersect with the current clip and when you
	removed it again it would immediately rebuild the entire clip. Now
	when you add or remove a clip it doesn't do anything immediately
	but just sets a dirty flag instead.

	* clutter/cogl/gl/cogl.c:
	* clutter/cogl/gles/cogl.c: Taken away the code to intersect
	stencil clips when there is exactly one stencil bit. It won't work
	with path clips and I don't know of any platform that doesn't have
	eight or zero stencil bits. It needs at least three bits to
	intersect a path with an existing clip. cogl_features_init now
	just decides you don't have a stencil buffer at all if you have
	less than three bits.

	* clutter/cogl/cogl.h.in: New functions and documentation.

	* tests/interactive/test-clip.c: Replaced with a different test
	that lets you add and remove clips. The three different mouse
	buttons add clips in different shapes. This makes it easier to
	test multiple levels of clipping.

	* tests/interactive/test-cogl-primitives.c: Use
	cogl_path_stroke_preserve when using the same path again.

	* doc/reference/cogl/cogl-sections.txt: Document the new
	functions.
