Drawing tool behavior in vertical scroll mode

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use "smart scroll" mode (it's vertical in my case)
2. Draw lines on two pages
3. Press "Done"

What is the expected output?
Drawings are saved on both pages

What do you see instead?
Drawings are saved only on one page

What version of the product are you using?
2.2.4

On what operating system?
Android 4.4

Moreover, when you clear the page (press Delete in drawing tools) then drawings 
of previous 1 or 2 or 3 pages, which was not involved in the latest drawing, 
can disappear.

PS: one more bag - when "thickest" line erased it's impossible to draw a new 
one on that place, even after restarting the app.
