[PATCH 0/8] Convert input co-ordinates to fixed-point

[Daniel Stone]

Hi,
The following patches (5 for the protocol and 3 for Weston) convert the
protocol to use signed 24.8 (well, 23.8 plus a sign bit) floats rather
than integers, which will help with transformed surfaces and
high-precision devices like graphics tablets.

There's also a couple of cleanup patches thrown in there that make
things a little bit clearer (at least, I think so).

Cheers,
Daniel
