Title: [MOD-636][MOD-635] Queued Painting

Rewrote rendering algorithm to allow for a number of enhancements:
- Retina display support [MOD-636]
- Fix erratic sharpening of previous drawings [MOD-635]
- Smooth erasing identical to how Paint behaves on Android
- Improved multi-touch drawing performance
- Quadratic smoothing of lines
Plus some white fix consistency fixes.
Added concept of a "Wet Paint View", which handles the current touch, until the user lets go with a finger.
