tdf#94851 can't use OpenGLSalBitmap with WinSalGraphics
Printing is done with the WinSalGraphics and not with
WinOpenGLSalGraphics on Windows even when OpenGL is enabled, but
the SalBitmap is still using the OpenGLSalBitmap which can't be
used with WinSalGraphics. So detect when the implementation of
SalGraphic is "wrong" and convert.
