Don't send EVT_TEXT_ENTER to controls without wxTE_PROCESS_ENTER
wxMSW always sent this event to multiline text controls, even when they didn't have wxTE_PROCESS_ENTER style, contrary to what was documented. Avoid sending this event unless wxTE_PROCESS_ENTER is used and add unit tests checking that multiline text controls don't get it without this style (but still do get it with it).

- wxDC::DrawCheckMark() draws the same shape under all platforms now, use the
|
||||
new wxRendererNative::DrawCheckMark() to draw MSW-specific themed check mark.
|
||||
|
||||
- wxTE_PROCESS_ENTER must be used to receive wxEVT_TEXT_ENTER events from even
|
||||
multiline wxTextCtrl, conforming to the documentation, but contrary to the
|
||||
previous behaviour in wxMSW, when these events were always generated in this
|
||||
case. Please add wxTE_PROCESS_ENTER style if you relied on the old behaviour.
