Feature: Multiple drawing pages

[hranmuthu]

During drawing mode, use left / right cursor keys to go to next drawing screen.

Initially when there is only current drawing screen, pressing left or right cursor key will create a new blank drawing screen. Then you can go back end forth on the drawing screens using cursor keys.

Hope this is clear. This will help when explaining a document or presentation, keep the old drawings on the screen and later go back to them.
