Collision avoidance for Lithuanian letters

[KrasnayaPloshchad]

I believe there are some necessaries to implement collision avoidance to certain Lithuanian letters as they can overlap each other, for example, in the word Sąjūdis, a-ogonek can overlap j a bit. So you need to implement either kerning or contextual alternates for fix.

I will wait from some Lithuanian users to file a complaint along with preferred solutions before looking further into this perceived defect.
