/*
* RICHED20 TODO (incomplete):
*
* - font caching
* - add remaining CHARFORMAT/PARAFORMAT fields
* - right/center align should strip spaces from the beginning
* - more advanced navigation (Ctrl-arrows, PageUp/PageDn)
* - tabs
* - pictures (not just smiling faces that lack API support ;-) )
* - OLE objects
* - calculate heights of pictures (half-done)
* - EM_STREAMIN/EM_STREAMOUT
* - horizontal scrolling (not even started)
* - fix scrollbars and refresh (it sucks bigtime)
* - hysteresis during wrapping (related to scrollbars appearing/disappearing)
* - should remember maximum row width for wrap hysteresis
* - find/replace
* - how to implement EM_FORMATRANGE and EM_DISPLAYBAND ? (Mission Impossible)
* - italic cursor with italic fonts
* - IME
* - most notifications aren't sent at all (the most important ones are)
* - when should EN_SELCHANGE be sent after text change ? (before/after EN_UPDATE?)
* - WM_SETTEXT may use wrong style (but I'm 80% sure it's OK)
* - EM_GETCHARFORMAT with SCF_SELECTION may not behave 100% like in original (but very close)
* - bugs in end-of-text handling (the gray bar) could get me in jail ;-)
* - determination of row size
* - end-of-paragraph marks should be of reasonable size
*
* Bugs that are probably fixed, but not so easy to verify:
* - EN_UPDATE/EN_CHANGE are handled very incorrectly (should be OK now)
* - undo for ME_JoinParagraphs doesn't store paragraph format ? (it does)
* - check/fix artificial EOL logic (bCursorAtEnd, hardly logical)
* - caret shouldn't be displayed when selection isn't empty
* - check refcounting in style management functions (looks perfect now, but no bugs is suspicious)
* - undo for setting default format (done, might be buggy)
* - styles might be not released properly (looks like they work like charm, but who knows?
