With version 342 you will get doubled texture size - that means 2048x2048 pixels - unless you're using a language whose characters use too much space (currently Japanese and Chinese)(448).

Now, the game allocates more texture space dynamically once the primary texture space fills up. More textures have the disadvantage of possible performance impact, but hey, it's better than not being able to use all of the plugins that you like at the same time

Right now, the pt console command only shows the last allocated plugin texture.
