New features

• added the possibility to move tools (ruler, compass, etc) using arrow keys.
• added a new Latex2SVG application converting Latex formulas to SVG, that you can then drag and drop on the board. Also supports mhchem for chemistry
• added CMake support for community-driven Linux builds, thanks to @letsfindaway and @Vekhir.

Improvements

• simplified the rules to be authorized to put a new text on the board, when close to another text box.
• Improved performances on document loading time, especially for heavy documents, containing a lot of annotations.
• changed delete icons' tooltip according to their text
• migrated Windows build from xpdf to poppler
• improved zLevel consistency and how the users can change it. A simple click on the "Layer Up" and "Layer Down" now simply increments or decrements the zLevel of the targeted object. Long click behavior remains unchanged.

Bug fixes

• workaround for an issue related to QTBUG-79216, where dead keys were simply ignored in web widgets. The workaround fixes completely the issue on Linux, but not on macOS. You can workaround
• the issue by giving focus of an input of the widget and pressing Next page then previous page on the Board toolbar, or by simply reloading the page when possible.
• fixed an issue where the mask would preserve aspect ratio when using the bottom right handle to resize it.
• fixed an issue where a newly created widget would not be visible until next launch
• fixed an issue where removing from board a newly created widget would erase it from library and disk
• fixed an issue where drag and dropping an object from a widget to the board would never trigger mouseReleaseEvent, ending with the widget being moved when not intended
• fixed an issue where object zLevels would not be correctly set
• fixed crashes occurring when using the 'Add' button's functionalities in Documents Mode
• fixed a crash occurring when trying to drag and drop an image already on the board
• fixed an issue where an image would be copy-pasted at bad off-screen positions on Windows
• fixed a crash occuring when directly exiting OpenBoard from Board Mode on heavy documents.
• fixed an issue where the scale of a pdf item was not preserved when copying the page to another document, with the help of @letsfindaway
• fixed an issue where the eraser was not working when completely inside polygon, thanks to @letsfindaway
• fixed incorrect sRGB profile and some files rights, thanks to @letsfindaway
• fixed an issue by avoiding access to uninitialized DisplayManager, thanks to @letsfindaway
• fixed ruler icons behaviors when zooming, thanks to @Vekhir
