OpenGL just sets GtkSalGraphics::bNeedPixmapPaint to true, and the
problem is specific to that flag (can be also enabled via
SAL_GTK_USE_PIXMAPPAINT=1).

Most other widgets are painted correctly in the GL case as they pass
around a drawable explicitly; do the same for ControlType::ListNode as
well in the GL case. The non-GL case still needs to go via the pixmap
render macros to have correct position, leave that unchanged.
