Element gaugeLeft(float ratio);
Element gaugeRight(float ratio);
Element gaugeUp(float ratio);
Element gaugeDown(float ratio);
Element gaugeDirection(float ratio, GaugeDirection);

• Add separatorHSelector and separatorVSelector elements. This can be used to highlight an area.
• Add the automerge decorator. This makes separator characters to be merged with others nearby.

2.0.0

Features:

Screen

• Add the automerge to the Pixel bit field. This now controls which pixels are automatically merged.
