89 The following function sets the child's parent pointer without adding the child to the children vector.
90 It's a hack (that should be deprecated?) to allow things like WSymbol to be created, do some drawing on
91 the surface and then be deleted again, leaving the drawing present.
92 A better design would be to create many WSymbols - one per symbol and leave them created - then the
93 automatic draw code (not written yet) will be able to redraw the symbols without all that code needing
94 to be in the derived boxx's draw method.

125 It's "Boxx" because "Box" was already taken.
127 BoxStack replaces Viewman and handles displaying a stack of root boxxs (boxxs with surfaces) on the screen.
129 Boxx relaces Box, Widget and parts of View and represents a box with or without a surface.
130 Let's call a Boxx with a surface a root box, and a boxx without a surface a child box.
132 A boxx with a surface (root) is like an old View and is handled by BoxStack.
133 A boxx without a surface (child) is like and old Widget and needs to be a child box of another boxx (root or not).
135 Don't add a boxx with a surface to another boxx. That isn't the design.
137 So, when you create a boxx, either that boxx calls createBuffer() on itself,
138 or some other box add()s the new box to itself.
140 Root boxxs can overlap each other - this is managed by boxstack.
141 Child boxxs within a parent boxx do not overlap each other.
142 However, a grandchild box can overlap a child box (but must be entirely contained within the child box).
144 TBBoxx replaces View but is now only a convenience class for the window dressing stuff. It isn't required anymore since
145 all the real work that view used to do is done in Boxx now.
147 Obseleted classes: Box, View, Viewman, Widget, others?
148 No code outside boxx should talk about surfaces anymore. Hopefully.
