The patch implements a software fallback for vertex blending in drawStridedSlow, fixing Bug #6955. Although vertex blending is an old and outdated extension, there are still many applications(games) relying on it nowadays. This because the extension is generally supported by Direct3D, either directly in hardware (using vertex programs) or in software.
This patch makes NOLF2 demo crashes.
