'---------------------------------------------------------
'
' Original implementation by 'AVE'(?), no readme attached.
' Heavily modified by Morten Hansen (eriol@e-dsign.com).
'
' In the initial modification, I added settings for:
' BackColor
' BorderColor
' ForeColor
' Padding
' BorderStyle
' TabSize
' DropShadow
' Autohiding
' Custom Font Properties:
' Name
' Size
' Bold
' Italic
' Underline
' StrikeThrough
'
' ...and did some general code 'cleanup' to make it suit my own
' coding style better.
'
'---------------------------------------------------------
'
' Changes:
' - 09.01.2003
' Added 'ShowTitle','Title','TitleAlignment' and
' 'TitleColor' properties, and 'About' method.
'
'
' Planned:
' - Rounded corners
' - Fade in/out (w2k/xp)
' - Transparency (w2k/xp)
' - Error handling
' - Icon
' - Gradient background
' - Header styles
'
' Bugs:
' - No known bugs at the moment. (1.0.1)
