The effect specifies whether underlining is turned on, while bUnderlineType
indicates the type of underlining.

The call to ME_SendSelChange cannot be done in ME_CommitUndo like it was
before, because it must be done after wrapping. Native richedit controls
send EN_CHANGE first, which is sent in ME_UpdateRepaint, so
ME_SendSelChange must be before this notification in ME_UpdateRepaint.
The border widths documented by msdn are in points which are 72 dpi, which
is not equivalent to pixels (normally 96 dpi). I pre-converted all the
border widths to 96 dpi resolution since this avoids needed to store
fractions, and often avoids the need for convertion to the displays
resolution.
Previously the only convenient way to get the start and end of the
selection was through offsets, which eventually need to get converted
back into items in the linked list storing the text. The new function
will help with eliminating these inefficiencies.
The application Blitzin2 was sending WM_VSCROLL messages to the
richedit control directly, when normally this message is supposed to
be a notification sent after the scrollinfo is set. Native richedit
controls always use the 16-bit value passed to this message to set the
scroll position for SB_THUMBPOSITION, rather than trying to find a
32-bit value through GetScrollInfo like I had previously done.
The missing return was to prevent automatic vertically scrolling when
style for it is not set, but is set for the horizontal scrollbar. I
initially missed this by testing with no autoscrolling on either
scrollbar.
When the richedit control is created without the ES_AUTOHSCROLL or the
ES_AUTOVSCROLL, then scrolling isn't done automatically when moving the
cursor with the arrow keys, drag selecting with the mouse, or even from
using the EM_SCROLLCARET (based on testing using a modified version of
wordpad).
The scrollbar visibility can be changed from SetScrollRange or
SetScrollInfo, but the visiblity that is a result of these calls are
not consistent with the calculation made by richedit controls to
decide whether to show or hide the scrollbars.
This prevents some needless searching for the start of the paragraph
from a run stored in a cursor. Usually a pointer to the paragraph is
already available when the cursor is set anyway.
