Deprecated and renamed presentation style attributes.

Starting with version 2.50:

The following presentation style attributes are deprecated (still implemented, but not to be used):
  • Window: backgroundImage
  • TextEdit: textSyntaxHighlight
The next presentation style attributes have been replaced by a new style attribute, or have been renamed:
