* Allow using relative path in MacOS for development builds
* [macOS] Fixes RT "cache"/"config" folder not located in the right place
In actual "dev" branch, RT "cache"/"config" folder is located in
"~/Application Support/RawTherapee" folder instead of
"~/Library/Application Support/RawTherapee" folder (as in v5.8 release
and discribed in RawPedia). Moreover, "CACHE_NAME_SUFFIX" cMake option
was not anymore considered.
* [macOS] Remember RT window position correctly, fixes#3209
As described in GTK documentation, some OS Windows Manager do not
consider setting window size and position before it is completely
created (which seems to be the case for macOS). In this commit,
restoring window size/position is now done after its creation.
Morevover, macOS menu bar height is now considered.
- Fixes segfault when modifying "Advice tooltips" option in Preferences
panel in "Multiple editor" mode
- Removes dedicated Locallab help button (will be managed directly in
RawPedia website)
- Fixes issue when switching to "Normal" mode with Retinex Locallab
tool.
The `version` value from the `Options` file is compared to the harcoded
value (computed at build time) of the running application. If the major
or minor version is different, the `svg2png` folder is cleaned at
startup-time.
