ClearTypeSettings registry key

I want to add ClearType support but I got a BGR LCD display.

I tried setting the registry key
HKLM\System\GDI\ClearTypeSettings
NativeOrientation = 180

The fonts are still rendered using RGB order.
Is there any way to make ClearType font rendered in BGR order?

I also tried to use SetClearTypeBltMasks to swap Red and Blue Blt Mask in
the display driver, but the fonts are still not correctly rendered.

Problem fixed.
I return the BGR Bit Masks in DrvGetMasks in the display driver. ClearType
fonts work on BGR display then.
