Subject: Add environment variables for Pinch and Rotation gesture
X-Git-Tag: dali_1.4.57~1^2
X-Git-Url: http://review.tizen.org/git/?p=platform%2Fcore%2Fuifw%2Fdali-adaptor.git;a=commitdiff_plain;h=2b48b6e75650cc6d179e731df79d4965aa76a97d

Add environment variables for Pinch and Rotation gesture

DALI_PINCH_MINIMUM_TOUCH_EVENTS
DALI_PINCH_MINIMUM_TOUCH_EVENTS_AFTER_START
DALI_ROTATION_MINIMUM_TOUCH_EVENTS
DALI_ROTATION_MINIMUM_TOUCH_EVENTS_AFTER_START

They represent the minimum touch events count required for a gesture
