// --------------------------------------------------------------------------------------
//  pxStaticText
// --------------------------------------------------------------------------------------
// Important:
//   Proper use of this class requires using it's custom AddTo( wxSizer& ) method, in the
//   place of wxSizer.Add().  You can also use the += operator (recommended):
//
//     mySizer += new pxStaticText( this, _("omg translate me?") );
//
// 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 calcuated 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.
//
// The first one is very hard to fix properly.  Currently this class employs a hack where it
// grabs the "ideal" fitting width from it's containing panel/window, and then wraps text to
// fit within those confines.  Under this design, pxStaticText controls will typically be the
// "regulators" of the window's display size, since they cannot really participate in the
// normal sizer system (since their minimum height is unknown until width-based sizes are
// determined).
//
// Note that if another control in the window has extends that blow the window size larger
// than the "ideal" width, then the pxStaticText will remain consistent in it's size.  It
// will not attempt to grow to fit the expanded area.  That might be fixable behavior, but
// it was hard enough for me to get this much working. ;)
