Bug Description

I am testing utouch-grail with a multitouch touchscreen. It seems that under certain circumstances you don't get events with status GRAIL_STATUS_END for completed gestures.

I use a slightly hacked grail-gesture to watch the events. Using mask 0x09 I do get the expected sequence:

gesture 0 7 345 2 - -1.106227 -0.852015 1 - 0
gesture 0 7 345 2 - -1.151160 -0.853480 1 - 1
[... repeated]
gesture 0 7 345 2 - -1.177045 -0.784615 2 - 2
gesture 3 9 345 2 - -1.262027 -0.784487 2 - 0
gesture 3 9 345 2 - -1.278632 -0.784487 2 - 1
[... repeated]
gesture 3 8 345 2 - 0.000000 0.000000 0 - 2

However, when using mask 0x10009 (adding GRAIL_TYPE_TAP2) the sequence omits the END-event for the first single tap gesture:

gesture 0 0 345 2 - -1.061294 -0.906716 1 - 0
gesture 0 0 345 2 - -1.078877 -0.906716 1 - 1
[...repeated]
gesture 0 0 345 2 - -1.226374 -0.903761 1 - 1
gesture 3 2 345 2 - -1.303541 -0.811766 2 - 0
gesture 3 2 345 2 - -1.319658 -0.810243 2 - 1
[...repeated]
gesture 3 2 345 2 - 0.000000 0.000000 0 - 2
