Subject: xinput: RawEvents: support lists axisvalues and axisvalues_raw
X-Git-Url: http://git.demorecorder.com/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d8e9abc8019a8f1da90ae779617b93f24fe3239;hp=fd9f1ade9605efe7c443d962134c4ded6c54f565;p=free-sw%2Fxcb%2Fproto

xinput: RawEvents: support lists axisvalues and axisvalues_raw

Support the lists axisvalues and axisvalues_raw in RawEvents.
These are RawKeyPress, RawButtonPress, RawTouchBegin and their eventcopies.

The length of both lists is determined by the number of bits set in the
list valuator_mask. This is solved in the same way as for event KeyPress.
