vl/compositor: fix weave shader bugs
Writemask was XY instead of YZ (thanks to calim for spotting it).
The pixel calculation resulted in the pixel always being off by one.
If y was .5:
y' = round(y) + 0.5 = 1.5
Fixing this also means the LRP function has to swap the pixels it, since
it's now the other way around for top/bottom.
WIth these fixes only chroma for top and bottom pixel rows are wrongly interpolated
in my test program:
