svn commit: r346761 - head/lib/libvgl

New Revision: 346761
URL: https://svnweb.freebsd.org/changeset/base/346761

Log:
  Use __VGLBitmapCopy() directly to show the mouse cursor.  The mouse
  cursor must be merged with the shadow buffer on the way to the screen,
  and __VGLBitmapCopy() now has an option to do exactly that.  This is
  insignificantly less efficient.
