[ ] On Rhythm draw, draw to Strip.Bitmap instead of List
- [x] Create Bitmap, create graphics context Graphics.FromImage()
- [x] Draw to graphics context (see clip below)
[ ] Scroll Bitmap instead of drawing Points
- [x] Display Image instead of Canvas
- [ ] Use CroppedBitmap to crop the Bitmap to only display desired portion
[x] Profile CPU use? See if 12L ECG less choppy?

Important: Broken fixes and To-Do's:

[x] Re-implement ECG grid background as its own WPF Image (add Z-Index).
[x] Remove debug code
- [x] Trace.BitmapToImage() saving each render to temp folder

Performance is already much better just drawing to Bitmap and displaying BitmapImage; not necessary to scroll Bitmap.

Performance goals achieved!
