 100 function wrappers for wxPython system dialogs
 101 Author: Kevin Altis
 102 Date:   2003-1-2
 103 Rev:    3
 104
 105 This is the third refactor of the PythonCard dialog.py module
 106 for inclusion in the main wxPython distribution. There are a number of
 107 design decisions and subsequent code refactoring to be done, so I'm
 108 releasing this just to get some feedback.
 109
 110 rev 3:
 111 - result dictionary replaced by DialogResults class instance
 112 - should message arg be replaced with msg? most wxWindows dialogs
 113   seem to use the abbreviation?
 114
 115 rev 2:
 116 - All dialog classes have been replaced by function wrappers
 117 - Changed arg lists to more closely match wxWindows docs and wxPython.lib.dialogs
 118 - changed 'returned' value to the actual button id the user clicked on
 119 - added a returnedString value for the string version of the return value
 120 - reworked colorDialog and fontDialog so you can pass in just a color or font
 121     for the most common usage case
 122 - probably need to use colour instead of color to match the English English
 123     spelling in wxWindows (sigh)
 124 - I still think we could lose the parent arg and just always use None
