Dylan Smith 94146a72ad richedit: Removed some unused invalidation code.
The ME_InvalidateFromOfs and ME_QueueInvalidateFromCursor functions are
never called, and the nInvalidOfs variable had its value set but never
used.

Dylan Smith 902afbc65b richedit: Prevented using NULL hwnd for certain operations.
Certain operations will simply not be done for windowless richedit
controls, such as WM_PAINT which isn't done for windowless richedit
controls since ITextServices provides a TxDraw method.

Dylan Smith 05c788ac6f richedit: Used ITextHost methods to avoid using window handle directly.
The methods in ITextHost are mostly thin wrappers around functions that
take a handle to a window as their first parameter.  This patch just
uses the wrapper functions provided by ITextHost instead of using the
functions that require a handle to a window that the editor might now
have (for windowless richedit controls).

Dylan Smith 6df4148b04 richedit: Prevent redundant rewraps when scrollbar is shown.
A common case for richedit controls are that a large amount of text is
set initially with word wrap enabled.  This causes the initially
wrapping of the text, which also calculates the text length.  After
this the vertical scrollbar will be shown, which causes the text to be
rewrapped again.  After this there are two redundant rewraps that are
done which this patch eliminates.

Dylan Smith a16db0afc6 richedit: Scroll up with less than page of text with ES_DISABLENOSCROLL. 2009-01-06 12:51:41 +01:00
Dylan Smith 97a83147b3 richedit: Avoid re-calculating positions found in wrapping for painting.
When the text is wrapped, the positions for all the runs, paragraphs,
and cells are already calculated and stored.  The only thing left to do
for painting is to offset them by the formatting rectangle and the
scroll position.

Dylan Smith dc03b6b2f2 richedit: Removed redundant editor height variables and calculations.
During wrapping there were three different heights that were being
stored, with only one of them being done correctly.  The other ones
failed to incorporate the height of the paragraph or row, so ended up
being incorrect.

Dylan Smith 297716e01c richedit: Made sure text is offset by formatting rectangle.
The formatting rectangle is set with EM_SETRECT, and retrieved with
EM_GETRECT, so it corresponds to rcFormat in the code.  This defines the
area that the richedit control should draw the text so that it is
offset by the top-left corner of the formatting rectangle, and clipped
so that it doesn't draw past the bottom or right hand side.  Thus this
is important for implementing windowless richedit controls to not
interfere with the rest of the window.

the text using system colours for the background and the text.
