Using pen to select topbar's buttons leads to writings artefacts

The reason for that is to seek on the editable area provided by the boox sdk. When the toolbar is shown/hidden this area has to change, and right now the implementation - although trying to achieve this result - seems to be buggy.

I thought I saw an example somewhere of dynamically adjusting exclusion zones, while leaving the overall rectangle alone. I may be misremembering, but it might be worth looking into.

Edit: This is the example I was thinking of. Not quite what I thought it was, but it still might do the trick: https://github.com/onyx-intl/OnyxAndroidDemo/blob/master/app/src/main/java/com/android/onyx/demo/scribble/ScribbleTouchHelperDemoActivity.java#L137
