Stefan Dösinger 85af0b2943 wined3d: Don't emulate clipplanes with ffp vp and fix a wrong if condition. 
b2f09fd204 accidentally got the
device->vs_clipping check wrong. The FFP replacement should emulate
clipping if GL can't do this natively with vertex shaders, not the
other way. Also don't emulate clipping if we're using fixed function
vertex processing because (a) clipping is always supported by GL in
this case, and (b), fragment.texcoord[7] is undefined. (Or in the
worst case set to something bad by the app).

/* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,

* two chroma(U and V) values. Each macropixel has two luminance values, one for
* each single pixel it contains, and one U and one V value shared between both
* pixels.
*
* The data is loaded into an A8L8 texture. With YUY2, the luminance component
* contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
* take the format into account when generating the read swizzles
*
* Reading the Y value is straightforward - just sample the texture. The hardware
* takes care of filtering in the horizontal and vertical direction.
*
* Reading the U and V values is harder. We have to avoid filtering horizontally,
* because that would mix the U and V values of one pixel or two adjacent pixels.
* Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
* regardless of the filtering setting. Vertical filtering works automatically
* though - the U and V values of two rows are mixed nicely.
*
* Appart of avoiding filtering issues, the code has to know which value it just
* read, and where it can find the other one. To determine this, it checks if
* it sampled an even or odd pixel, and shifts the 2nd read accordingly.
*
* Handling horizontal filtering of U and V values requires reading a 2nd pair
* of pixels, extracting U and V and mixing them. This is not implemented yet.
*
* An alternative implementation idea is to load the texture as A8R8G8B8 texture,
* with width / 2. This way one read gives all 3 values, finding U and V is easy
* in an unfiltered situation. Finding the luminance on the other hand requires
* finding out if it is an odd or even pixel. The real drawback of this approach
* is filtering. This would have to be emulated completely in the shader, reading
* up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
* vertically. Beyond that it would require adjustments to the texture handling
* code to deal with the width scaling
