old code which didn't send them anyhow removed). It also allows to veto the

2. wxBitmapBuuton doesn't lose its bitmap any more
3. wxImage::ConvertToBitmap() doesn't crash if image is !Ok() but just
returns wxNullBitmap.
4. wxProgressDialog looks much nicer under Windows and its estimated/elapsed/
remaining time fields actually show some non random numbers now
5. MDI client window doesn't flicker because wxMDIParentFrame doesn't position
it at (0, 0) first before moving it to correct location
6. other minor fixes...
