Vadim Zeitlin 05942059ef Refresh wxMSW wxStaticBitmap when its size changes.
As MSW native control centers the image, it must be entirely redrawn when the
area in which the image is centered changes, but it doesn't happen by default,
so do it ourselves explicitly.

Also explain that this centering behaviour is platform-specific and shouldn't
be relied upon.

Closes #4564.
