Remove StatusBar, replace with discoverable tooltips on overlay

[Alecaddd]

Context

The purpose of the Bottom StatusBar was to have a place to list "tips and hints" for tools, not easily discoverable via accelerators.
For example, when the user selects the Rectangle Tool, the follow message will appear: Hold **Ctrl** to keep a 1:1 ratio of width and height | Hold **Shift** to grow from center point

Proposal

• Removing the StatusBar to have a cleaner UI and gain more space.
• Show the "hints" as an overlay widget in the bottom left corner of the Canvas area.
• Allow users to hide the "hints" from the Preferences Panel (great for expert users who don't need "tutoring")

This should be very easy to implement now since the Canvas has an OverlayBar can be activated/deactivated with the canvas_notification signal.

Moving the target milestone to Beta since we don't have enough shortcuts for our drawing tools to justify this implementation right now.

Hi! I took a look at good first issues and so found this. But when i use the rectangle tool (insert -> shapes -> rectangle) I don't see the bottom StatusBar. Any hints for a new user?

It hasn't been implemented yet

:D Then maybe I'm misinterpreting the purpose of this issue. To me it looked that's how you do things currently and you want to remove the StatusBar in the future.

No, sorry if it's not clear.
The status bar has been removed, but the tooltip overlay hasn't been implemented yet.
That's why nothing is visible when you select a tool.

Oh I see. I'll read the code the next couple of days. Maybe I can find the right spot to add it.
