This code creates the structures and the pipeline selection, as well
as the caps filling. It does not yet move the actual code around,
since this will be a bigger task.

This should do the same as the existing code, but it is more obvious.

This is a further separation of the sampler state, and a preparation
to move the nv texture shader stuff to its own pipeline implementation.

When a sampler is changed and unconditional NP2 textures are not
supported, the texture matrix may need adjustment. The sampler state
function checks for that, and calls the texture transform setting
function in that case. However, samplers are a misc state, and the
texture transform flags a vertex state.  Thus split up the code and
move the matrix changes to the vertex side.

Since atifs is only doing the fragment pipeline replacement right now
there is no need for the shader backend structure any longer. The ffp
private data is stored in new fragment pipeline private data(which
could potentially be set to equal the shader private data if needed).

It isn't related to the shader backend any longer. The nvts_enable in
the ffp code isn't quite right as well, it should be moved away once
there is a dedicated nvts fragment pipeline replacement

In version 1.0 of the richedit controls highlighting is done by
inverting the colours.  Version 2.0 and up highlight instead draw
the text using system colours for the background and the text.
