My First QML App - KidsDraw

I wrote my first QML application.  It is a simple app that allows you to draw with a touchscreen.  There are multiple colors to select from.  The draw surface supports multi-touch so you can use two fingers to draw two lines at once.  It was designed for my son to use.  He doesn't like it when I use my laptop without him.  He really likes my laptop since he can touch the screen and things happen.  The only problem so far is he uses more than two fingers.  In Ubuntu, the system recognizes 3-finger and 4-finger gestures, so my son can easily get out of the program by mashing his hand on the screen....which he does regularly.

The app is very bare bones.  It does not contain any automated test cases.  It assumes more of a laptop or tablet display, since it puts a row of color buttons that probably won't fit on a phone.
