A helper class to fit overflowing text inside the textbox area, by either expanding the textbox height or compacting the font size.

• exists returns true whether textbox contains overflowing text, false otherwise,
• expand modifies the textbox height to fit the overflowing text,
• compact scales font size down until all the text fits inside the textbox.

// Check whether textLayer contains overflowing text
Overflow.exists(textLayer);

// Modify the textbox height to fit the overflowing text
Overflow.expand(textLayer);

// Scale font size down until all the text fits inside the textbox
Overflow.compact(textLayer);
