NullPointer in BaseGraphics.drawTextureVO

[Kevin Rushforth]

Is this from FX 2.2.x or FX 8? The stack trace suggests an earlier 
version of FX. The only thing I can think of off hand is that the HW 
texture couldn't be created, probably because you ran out of resources. 
There are a few issues relating to this, which we believe are fixed in 
FX 8 with the implementation of RT-25323.
