accuracy for point of query mode

[Janeks Kamerovskis]

Hi!

I faced with problem in subj. when doing queries on point layer.

I seems that user should point to exact pixel to get query on point layer,
because I got info on point just in very rear cases.

But stop ...
It could be also problem of my javascript on client side -  I should to make
some debugging ... 

But anyway is it possible to change/specify accuracy for point of query
mode.
