+ * Pure software drivers don't need to worry about this -- if they stick to the
+ * GDI API then will integrate with the Desktop Window Manager (DWM) without
+ * problems. Hardware drivers, however, cannot present directly to the primary
+ * surface while the DWM is active, as DWM gets exclusive access to the primary
+ * surface.
+ *
+ * Proper DWM integration requires:
+ * - advertise the PFD_SUPPORT_COMPOSITION flag
+ * - redirect glFlush/glfinish/wglSwapBuffers into a surface shared with the
+ * DWM process.
