Unable to allocate direct buffer memory

[Kevin Rushforth]

This suggests that there might be a memory leak (possibly in uploading 
painter which I see you are using). Is this easily reproducible?

As for the other exception:

> java.lang.RuntimeException: Requested texture dimensions (32767x1137) 
> require dimensions (0x1137) that exceed maximum texture size (16384) 

Are you really trying to draw into a texture that big? If not, then 
either the error message is printing the wrong sizes (which is quite 
possible) or else something is causing a larger than expected size to be 
used.
