//  pxStaticText
// --------------------------------------------------------------------------------------
// This class's purpose is to overcome two fundamental annoyances in wxWidgets design:
//
//   * An inability to wrap text to conform to a fitted window (a limitation imposed by
//     wxWidgets inability to fit individual directions, ie fit widths and then fit heights,
//     which would allow a textbox to wrap text to a sizer-determined width, and then grow
//     the sizers vertically to fit the calculated text-wrapped height).
//
//   * Textbox alignment requires aligning both the textbox contents, and aligning the text
//     control within it's containing sizer.  If both alignment flags do not match the result
//     is typically undesirable.
