Last change on this file since 1379 was 1379, checked in by bln4, 5 years ago

Reimplementation of the functionality that limits a text item to one line by reducing font size. The user must now specify inject a width property (eg Width: 300) and inject the property 'SingleLineOnly: true' to cause the functionality to happen. This new version of the functionality also now works with pasting large amounts of content rather than adding a single character at the time. Also, this new version dynamically returns to the larger font size as the length of the text item decreases.
