D3D: Implement vertex blending in drawStridedSlow

[David Adam]

2009/1/25 Claudio Ciccani <klan at users.sf.net>

>
> 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 Although vertex blending is an old and outdated extension, there are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.
