* Use target_include_directories to specify include paths
* Specify project root (parent of rtgui and rtengine) as include path
* Replace relative includes with normal includes
The rtgui denoise luminance detail adjuster widget default value is
set to 50, but the procparams default is 0 causing some confusing
behavior: when enabling the denoise tool in the gui the luminance detail
value is set to the proc params default value (0), when resetting the
adjuster the values is set to 50.
This patch sets the adjuster default value to the procparams default
value like the other adjusters.
Option to disable noise reduction automatic gain for consistency between
photographs.
Fix automatic gain not being recalculated after changing the white level
correction.
Replaces the following deprecated Gtk classes throughout the codebase by their non-deprecated counterparts. Style, HBox, VBox, HPaned, VPaned, HScrollbar, VScrollbar, VSeparator, HSeparator, Stock, Table, VScale and HScale.
Collection of CSS and GUI improvements, cleanup of main CSS theme, introduction of highlight for enabled module.
Primary change is the modification of the module titles to better distinguish modules that are on or off. The text of a disabled module is now less bright, the corresponding icon is a slightly smaller version of the power icon. When activating the module, the text turns brighter and the icon slightly bigger and also brighter. Thanks to @TechXavAL for the icon work.
Secondary changes are related to the margins around several GUI elements, padding within elements and some accompanying borders. These changes hopefully make it easier to distinguish the various (sometimes crowded) GUI elements of modules. The panels have gotten a slightly 'outset' look.
Nested panels have a changed look where deeper nesting increases the background brightness slightly, instead of darkening it (old behaviour). This is done without a strong decrease in contrast.
The old theme is available as a legacy option. Due to hardcoded GUI changes needed for the new theme, the legacy version is not a 100% exact replicate. The @TooWaBoo theme's may also be slightly affected.
This turns `IdleRegister::add()` into a template function to make the
provided function pointers type safe. It also adds a `delete_data`
parameter to manage the provided data pointer even in `destroy()`.
Revised all Noise Reduction labels, now they are grouped by the sub-tool
they correspond to and are easier to translate by those who don't know
how to search through the code.
Used generic labels where possible (curve, slider).
Renamed "Quality" to "Mode", and "Method" to "Color space".
Closes#3854
