LK Script progress bar does not resize to fit text

[cpaulgilman]

Describe the bug

The LK Script progress bar's Close button is hidden when text has more than two lines. For example, in Windows:

To Reproduce

1. Download and extract this LK script: lk-progressbar-size-test.zip
2. Run the script and note dialog does not resize to fit text.

Expected behavior

Best solution would be to add size parameters to function so that the progressbar size can be set when the function is called. We want the progress dialog size to be static so it does not appear to move around the screen when the text changes.

Needs to work for Windows, Linux, and Macos, so pixel-based sizing is not ideal due to different font sizes across the platforms.
