[PATCH 0/6] property support for ptraccel

[Peter Hutterer]

So far, the new pointer acceleration code could be configured through
configuration options but not changed at runtime. This patch set adds support
for device properties in the pointer acceleration code. Heavily rebased and
bounced between simon and me a few times.

As part of this patch series, we introduce a new server-defined property
"FLOAT". This property can be used as type specifier for float properties.
Coupled with that, the XIToInt() and XIToFloat() auxiliary functions.

I'd especially like to get feedback on the float properties, I'm really not
sure if that's the appropriate method to send floats over the wire (it did
work during testing).

Cheers,
  Peter
