Bug 136250

Description:
when in slide show mode and using the pen option, there are several bugs such as:
1. changing the pen colour does not have any effect. I still get red
2. Annotations stay there if I close the slide show
3. Annotations cannot be erased using the "Erase all ink on slide" option once you close the slide show. Even if they get erased once, they re-appear if you re-launch the slide show

Steps to Reproduce:
1. change settings to use the pen in slide show
2. draw something
3. try to change colour and re-draw
4. close the slide show
5. Erase the ink with the corresponding option
6. close slide show and re-open
7. Ink is still there and may appear in several slides

Actual Results:
no colour change, no ink was erased

Expected Results:
change pen colour, erase ink when the slide show is closed, erase ink when the option is selected


Reproducible: Always
