If moving the caret around a document in Microsoft Word with report spelling errors turned on (default), there is a noticable lag before the braille display is updated. Turning off reporting of spelling errors definitely reduces the lag.
When collecting text from MS Word, we currently check for a spelling error on every word, which would mean a great deal of calls.
Perhaps we should collect all spelling error offsets at the start and match them as we move through the text by word.

Fix a possible buffer overrun which may have caused a crash in MS Word (picked up by MSVC RTC). Re #3785

VT_BOOL uses 16 bit values, so either VARIANT_BOOL or BOOL should be used. bool (c++) is only 8 bit which is not enough. The rest of calls with VT_BOOL were using BOOL 32 bit.
