There's only one little problem that will probably be solved after Alpha1: if you have multiple accounts, all of them will set the avatar icon and the user will see just the last icon set.
* Added BitmapView::Bitmap() method.
* BitmapView::SetBitmap() now doesn't resize the view anymore.
* BitmapView has now a minimum size of 32x32.
* Draw bitmap on BitmapView using B_FILTER_BITMAP_BILINEAR.
* StatusView sets now explicit max and preferred size to 50x50 for the avatar icon view and doesn't resize the bitmap explicitely.
* Small style violation fixes.
