Subject: [PATCH] Let's go ahead and throw this in here, should bring support
 of Intel IGP back in with DX9.... I can't actually test this for an obvious
 reason, but I figure while Windows is broken anyway, go ahead with it.

git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7707 8ced0084-cf51-0410-be5f-012b33b47a6e

That should fix the seg faults on IGP chipsets.

git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7715 8ced0084-cf51-0410-be5f-012b33b47a6e

Compile fix.
