This is a dupe of issue 32. Out of memory errors should be handled more 
gracefully. 

A RGBA32 texture consumes 1 GB of mem. If you request mipmap generation that 
requires
16*16*4*sizeof(float) = 4 GB more. This is more than the addressing space 
available
on a 32 bit OS, and that causes an out of memory error.
