Position of annotation not so precise

[renanstig]

Hi,
I'm using your library and I do hope you can help me out on this.
I've made some modifications in the library, which the TileView received a longPress and it adds a annotation right in the point the user is pressing.

It works fine when the PDF doesn't have many levels, but I'm using one which has 7 levels and when I try to get the position (x,y) in the TileView , it is a little bit off, usually a bit left off the position I actually pressed, do you have any clue why?

Best regards,
Renan
