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.
Previously, changing to a different scope was done by clicking the scope
type button and cycling through all scopes. This commit decreases the
number of clicks needed to switch between two scopes by adding a radio
selector. The radio buttons can be shown or hidden by pressing the scope
type button. This commit also makes the raw histogram one of the scope
types.
Perspective control line type is automatically set when first drawn. The
type is determined by the line's angle. Buttons for specifying which
line type to draw are removed.
SVG splash screen template moved to splash_template.svg
splash.svg now contains just the relevant part shown by RawTherapee.
splash.svg updated for 5.8.
Resolve minor conflict in ImProcFunctions::transformGeneral and add new
arguments for use of ImProcFunctions::needsTransform in
PerspectiveCorrection::autocompute.
RawTherapee is getting support for SVG icons and images #3547#4803
and so our svg image need to have a clean design in order for librsvg
to render them correctly. I redrew the RawTherapee logo from scratch,
trying to keep things as simple as possible. I also merged rt-logo.svg
into rt-splash.svg.
