Current Behavior

When using the horizontal layout and a scale larger than one, the width of the note area isn't scaled properly, resulting in the end of the song not visible.

Expected Behavior

Width of the

where the notes are rendered should be increased with scale.

Steps To Reproduce

Easy to reproduce on https://alphatab.net/docs/playground

1. Select Horizontal layout.
2. Set the scale > 1
3. Scroll to the end of the song, you will se that the end of the song is cut off.
4. If you play the playhead will go past the visible area.
