You forgot the 'i < ' before the 'This->parent.max_clipping_planes'.

And here, you renamed the dwIndex (the official MSDN sanctionned variable
name) to Index :-)

Usually, we keep the Main declaration even if we never use it and replace it
with a GL one. This is always to help an hypothetical new driver.

Same comment for Index here too.

Otherwise, looks good :-)
