X-Git-Tag: 0.1.0~170
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dcaca098f8d5afd0e60141058c89093741a5eeb3;p=platform%2Fupstream%2Flibinput.git

compositor-drm: Enable seat constraining when configured in weston.ini

This change tweaks weston_pointer_clamp to take into consideration if a
seat is constrained to a particular output by only considering the
pointer position valid if it is within the output we a constrained to.
This function is also used for the initial warping of the pointer when a
constraint is first established.

The other two changes are the application of the constraint when either
a new device added or a new output created and therefore outputs and
input devices can be brought up in either order.

v2: the code in create_output_for_connector has been spun off into a
new function setup_output_seat_constraint (Ander). The inappropriate
warping behaviour has been resolved by using weston_pointer_clamp
(Pekka).
