174 - ES_READONLY (I'm not sure if beeping is the proper behaviour)
180 - ES_WANTRETURN (don't know how to do WM_GETDLGCODE part)
187 * RICHED20 TODO (incomplete):
189 * - messages/styles/notifications listed above
191 * - add remaining CHARFORMAT/PARAFORMAT fields
192 * - right/center align should strip spaces from the beginning
193 * - more advanced navigation (Ctrl-arrows)
195 * - pictures/OLE objects (not just smiling faces that lack API support ;-) )
196 * - COM interface (looks like a major pain in the TODO list)
197 * - calculate heights of pictures (half-done)
198 * - horizontal scrolling (not even started)
199 * - hysteresis during wrapping (related to scrollbars appearing/disappearing)
201 * - how to implement EM_FORMATRANGE and EM_DISPLAYBAND ? (Mission Impossible)
202 * - italic caret with italic fonts
204 * - most notifications aren't sent at all (the most important ones are)
205 * - when should EN_SELCHANGE be sent after text change ? (before/after EN_UPDATE?)
206 * - WM_SETTEXT may use wrong style (but I'm 80% sure it's OK)
207 * - EM_GETCHARFORMAT with SCF_SELECTION may not behave 100% like in original (but very close)
209 * Bugs that are probably fixed, but not so easy to verify:
210 * - EN_UPDATE/EN_CHANGE are handled very incorrectly (should be OK now)
211 * - undo for ME_JoinParagraphs doesn't store paragraph format ? (it does)
212 * - check/fix artificial EOL logic (bCursorAtEnd, hardly logical)
213 * - caret shouldn't be displayed when selection isn't empty
214 * - check refcounting in style management functions (looks perfect now, but no bugs is suspicious)
215 * - undo for setting default format (done, might be buggy)
216 * - styles might be not released properly (looks like they work like charm, but who knows?
