* Improves RT window events detection and RT window position computation
* Fixes some limitations in specific cases for Windows and MacOS
* Fixes RT window not restoring saved position at startup
- When maximized at startup, RT window position wasn't restored from
options file. So when unmaximazing RT, position was set to up left
corner instead of restored one
- Other fix: Removed some uses of deprecated Gtk functions
* Improves RT window management for independant edit window mode
Other fixes:
- Monitor ID wasn't correctly computed
- Removes some other deprecated functions uses
- Removes debug printf
* Fixes editor window aspects not restored in MEOW mode on Linux
Other fixes:
- Removes some Gtk warnings when adding a new editor panel in MEOW mode
- Adds robustness to avoid RT windows outside screen at startup loading
corrupted options file with negative position values
* Fixes incorrect max position saturation in dual screen configurations
