================================

- wxFontData::GetColour() now returns a const colour
- wxDC objects can't be created directly now (this never worked, now it doesn't
  even compile)
- For all wxInputStreams, Eof() becomes true after an attempt has been made
  to read _past_ the end of file.

- wxMBConv::cMB2WC() and cWC2MB() take size of the input buffer and return
  length of the converted string in all cases now.
- wxHtmlWindow::OnCellClicked() now returns bool.
- wxHtmlCell::OnMouseClick() was deprecated and replaced with
  wxHtmlCell::ProcessMouseClick(); old code overriding OnMouseClick() will
  continue to work with WXWIN_COMPATIBILITY_2_6, but should be rewritten to
  use ProcessMouseClick().
- wxHtmlCell::GetCursor() was deprecated and replaced with
  wxHtmlCell::GetMouseCursor(); old code overriding GetCursor() will
  continue to work with WXWIN_COMPATIBILITY_2_6, but should be rewritten to
  use GetMouseCursor().
