Subject: [PATCH] [PAINT] - Fix the "grey panel" bug when doing File --> New. -
 Add the possibility, when doing File --> New, to save the drawing the user
 did before actually reset it, and take into account whether he/she cancels
 the operation in the middle. Patch by Marco Vaiano, slightly modified by me.
