[fixed](https://love2d.org/wiki/RevoluteJoint:getMotorTorque) Having to provide invdt seems weird though and should be changed to dt imho.

Would it be acceptable to get `dt` automatically if it wasn't provided in the call? Is changing `invdt` to `dt` a good idea?

Sure, I'll gladly complain about anything that isn't as perfect as it should be! lol Thanks for the effort and I commend your taste in music too if you like...

You can test this by adding `love.timer.sleep(.2)` at the bottom of `love.draw` in `main.lua`. It's gonna be pretty difficult to click anything. The same problem was apparently occuring in [`Keyboard.lua`](https://github.com/flamendless/Slab/blob/97f8df3dc5803566650a6bc98cf27539c4a5b6b0/Internal/Input/Keyboard.lua#L69-L71)....

This is now fixed for clicks, but still an issue when resizing a window at low framerates. Possibly other places too.

Please leave it alone for the time being, until I'm done working on the DrawCommands module. It may fall all into place if I understand it better, and it may...

[Another example](https://github.com/flamendless/Slab/blob/97f8df3dc5803566650a6bc98cf27539c4a5b6b0/Internal/UI/Window.lua#L698) This string should be cached in `ActiveInstance` if possible instead of regenerating it every time.

After looking at the code in more detail I realize it's going to be a bit more complicated. [This](https://github.com/flamendless/Slab/blob/97f8df3dc5803566650a6bc98cf27539c4a5b6b0/Internal/UI/Button.lua#L53-L65) part should use `local`s instead of modifiying the Options table (which...

Closed? What about the rest of the code, lol
