Prevent the default wxWindow-level wxEVT_ERASE_BACKGROUND handler from being
used in wxUniv for wxHtmlWindow. This is unnecessary as it has its own handler
anyhow and also doesn't work for some reason as erasing wxMemoryDC by drawing
a solid rectangle over it seems to be broken in at least wxX11.
Work around this problem by erasing the background in wxHtmlWindow itself if
no user-defined (as opposed to any, including one defined in wxWindow itself)
handler for this event exists.
Closes#13880.

This fixes generation of EVT_CONTEXT_MENU for mouse clicks in wxHtmlWindow
under MSW: it wasn't generated before because we always ate the right mouse
clicks.
Closes#2465.

Applied patch by snowleopard2 fixing a bunch of typos such as misspellings and double words in the documentation. Combined the patch with some local queued typos waiting to be committed as well as adding new typo fixes inspired by the patch.
Function names with American spelling were not changed nor was third-party code touched. The only code changes involve some changes in strings that are translated ("Can not" -> "Cannot").
Closes#13063 (again).

While wxHtmlWindow doesn't support mixing LTR and RTL contents we can indeed
try to make it render pure RTL stuff correctly by setting up the wxDC used for
drawing accordingly.

Use wxDELETE[A]() functions which automatically NULL out their arguments after
deleting them instead of doing it manually.

wxHtmlWindow::CreateLayout()'s algorithm was both naive (not properly
accounting for scrollbar visibility changes during layout) and broken
(incorrectly rounding when computing scroll steps and adding
GetCharHeight() value to the height in an attempt to mitigate the
harm).
This algorithm should properly for scrollbars in all situations.
Rounding is done in such way that the content is fully viewable, while
at the same time not showing scrollbars needlessly.

The "slight code simplification" of r61772 broke the code as it could now
crash if dangling m_Cell pointer was used during parsing. Revert it and add a
comment explaining why the code is written in the way it is.

No need to check whether the pointer is NULL before deleting it nor to assign
NULL to it if it's going to be immediately reassigned on the next line.

1. Avoid crashes under OS X due to attempts to copy window contents to the
backing store bitmap: this doesn't work under OS X so avoid it by always
painting the background from OnPaint() itself, while still generating the
erase background events for compatibility.
2. Don't double buffer wxHtmlWindow drawing if the window is already double
buffered.
3. Don't allocate backing store bitmap on the heap, this is useless as bitmaps
are already pointer-lile -- so just use invalid bitmap instead of NULL
bitmap pointer.
4. Update the html/test sample to show the effects of custom erase background
handler in wxHtmlWindow (it overrides the background bitmap painting).

of a simple typedef to "Node *" to be able to initialize it with NULL in ctor
which makes the behaviour of the code with and without wxUSE_STL the same.
The price to pay is that the code like
wxList:compatibility_iterator ci;
ci = cond ? list->GetFirst() : wxList::compatibility_iterator();
doesn't compile any more and has to be replaced with (more clear anyhow)
wxList:compatibility_iterator ci;
if ( cond )
ci = list->GetFirst();
