What this commit does is keep the same code logic while moving to
GeglColor. Yet it's not **really** space-invaded yet. What we need to do
now:
1. Take into account the image space, and this is what we must navigate
through, in particular for various representations of RGB or HSV.
I.e. that if the active image is in anyRGB, the RGB values shown must
be within anyRGB. Right now, everything is still shown/used as sRGB
(even though it's properly retrieved and transformed to the target
space thanks to GeglColor).
2. Show space info to make things clear and explicit, by adding some
label somewhere.
3. Allow to switch between image and softproof spaces, regarding
out-of-gamut display. I.e. that while RGB/HSV must be shown within
the image space (assuming it's anyRGB), we may want to show
out-of-gamut area (pink areas) within the softproof space. This may
mean adding a checkbox. Or maybe simply taking into account whether
we are in softproof mode or not?
4. We can likely move off gimp_widget_get_color_transform() into using
gimp_widget_get_render_space() for display drawing. We don't need any
soft-proofing or black point compensation for any of these widgets so
pure babl is fine. Indeed we want to show any in-gamut color
correctly (and not transformed according to specific intents or
through soft-proofing). We will take care of the proofing case with
out-of-gamut area showing only.
5. In the various drawing functions, we should move to
CAIRO_FORMAT_RGBA128F. The color selection area might be wide enough
that it makes sense to be more accurate, especially as we are
essentially showing color gradients in 1 or 2 directions in these
various widgets.
- New libgimpcolor functions: gimp_color_parse_hex() and gimp_color_parse_name().
- GimpColorHexEntry is now space-invaded. Though recognized color names
and hexadecimal syntax are sRGB only (because CSS and SVG
specifications explicitly say that this syntax is for sRGB values), it
is possible to enter non-sRGB values with
gimp_color_hex_entry_set_color().
- GimpColorSelection is now space-invaded.
This includes improvements on the out-of-gamut colored corner being shown for
unbounded component types out of the [0; 1] range (with some small margin of
error to avoid e.g. a -0.0000001 value to show as out-of-gamut).
There are still improvements to be made on the color rendering. In particular,
it still draws as CAIRO_FORMAT_RGB24 cairo surface. We should probably move to
draw as CAIRO_FORMAT_RGBA128F eventually (more precision and even allowing to
draw unbounded colors with a possible option, instead of always clipping).
Also adding the libgimpwidgets API gimp_widget_get_render_space().
In GTK, a common scheme is to let a function creating a specific widget
to return a `GtkWidget *`, rather than the specific subtype, since you
often need to call API of GtkWidget, avoiding some useless casts.
For bindings however (and especially bindings to compiled languages),
this is a bit annoying, as you have to explicitly change the type of the
return value (downcast), which is not trivial (or at least desirable) in
each language.
Luckily, we can use `(type ...)` annotation for this use case, leaving
the C API unchanged, while improving the experience for bindings.
* Don't generate our own marshallers if they are available in GLib
already
* Don't set the c_marshaller parameter in `g_signal_new()` if it's a
default marshaller provided by GLib. See commit message of commit
39e4aa3c57 on why this is the case.
Documentation-wise in C, this doesn't matter a lot, but it allows
GObject-Introspection based bindings to use their built-in versions when
they want to render any kind of documentation (for example, docs for
Python plugins can render `%NULL` as `None`).
... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
- remove redundant frames, 3d-frames are gone anyway, so no need to
keep double out/in frames around
- give all color selector classes CSS names
- add/fix some theme CSS styles
Set the tooltip in GimpColorHexEntry itself and remove all other
tooltip setting. This just moves the translatable string sround in
libgimpwidgets/, and even removes it from app/.
even if we don't have private members (yet). Also make class padding 8
pointers in all headers. This commit moves nothing to private, it just
makes all headers consistent and adjusts .c files accordigly.
Redo the entire thing again:
- Rename the values of enum GimpColorSelectorModel to include "MODEL"
- Change GimpColorSelector API from set_model() to set_model_visible()
so visibility of each model can be toggled individually and is not
exclusive any longer
- The GUI is back to what it was before, except that the "GIMP" page
now honors the model visibility and has a resonable minimum height
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.
