[chalkboard] when using a pen the last part of a line is erased when lifting the pen #156

Moving the pen above the screen seems to switch the pen behavior to "erasing". This means that the end of each line is erased as soon as I lift the pen which is undesired. The "touch" behavior in contrast works correctly, lifting the finger does not activate erasing.

The chalkboard plugin is a totally awesome addition to reveal.js.

In general, from my experience (Samsung Galaxy S7 and pen, iphone, Fairphone) it is quite tricky to toggle editing/erasing modes given touch gestures only. It would be great to have a button for the eraser. On mobile devices during a presentation, sending a del command or a right-mouse click can be quite tricky.

The eraser function is changed in v4.2.2 and is no longer initiated by long press. Instead you can now find a sponge in the palette. Probably the erasing of the last part is no longer happening.
