m_cocoaNSBitmapImageRep (fixes multiple release bug).
* Add some debug messages for unimplemented wxMask::Create overloads.
* Implement mask creation w/ key color from 8-bpp grayscale bitmap.
This makes the mask image in the drawing sample's mask page work.

1. remove UseAlpha() on platforms that don't need it and call it automatically from ~wxPixelData instead of requiring explicit call; deprecate wxPixelData::UseAlpha()
2. don't call UngetRawData() if GetRawData() failed

1. perform deep comparison for the classes for which it makes sense in the
ports where this wasn't done yet
2. remove (shallow) comparison operators for the classes for which it does
not make sense (such as wxBitmap)
3. makes wxBitmap use COW on all ports
4. adds wxObject::IsRefTo()
5. centralizes and improves COW docs

* Added ability to create bitmaps from width/height
