[PATCH evdev 0/3] Preliminary support of multitouch (rev2)

[Benjamin Tissoires]

Here is finally the new set of patches to enable a preliminary support of multitouch into Xorg.

Changes since last time:

- squashed patches "Detection of multitouch device" and "Add the new valuators for multitouch"
- renamed the field mt_num_valuators to mt_current_touchpoint
- namespace for initialization functions of multitouch
- choose the number of touchpoints depending on the space available (MAX_VALUATORS) and the TrackingID
- comments
- sort the mt valuators to have ABS_MT_POSITON_X and ABS_MT_POSITON_Y first
- dropped the patch named "Keep the states of multitouch events" since the EV_SLOTS will allows us to avoid manually sorting the incoming data.

Cheers,
Benjamin
