Presentation styles changes

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The next presentation style attributes have been replaced by a new style attribute, or have been renamed:
  • CheckBox: nativeLook => customWidget (with same possible values)

    In version 3.00, the Checkbox.customWidget style attribute has been desupported, but reintroduced in version 3.10 for GBC with the "toggleButton" value.
