Radeon SUBPIXEL_X|Y.

[Jacek R. <pa...@fa...>]

Hi,

In radeonUpdateWindow and radeonUpdateViewportOffset functions in
radeon_state.c `tx' and `ty' values are calculated differently. In
UpdateWindow SUBPIXEL_X|Y values are added and in UpdateViewportOffset
it's not and compared to values which might have been calculated in
former function. The same goes for r200 driver.

BTW: What is SUBPIXEL_X|Y exactly used for?

Best,
