OK, here's another....

....I had a Performer 1.2 / IRIS GL app that explicitly used "subtexload"
I used the mode flags to subtexload ( with a value of 1 ) to specify that I
wanted to load 64x64 texel sub-tiles of packed 16bit texels. Even when I used
this method to load an entire 256x256 texture in 16 chunks this was jolly fast
in comparison to using TX_IDLE or subtexloading a 32 bit texture.

So here I am porting the code to Performer 2.0.... I use the Performer api to
do the loading but I know that I am loading 32 bit texels at the moment.

Question 1 - how do I get the nice fast 16 bit mode I used to have in IRIS GL
using the Performer API ?

Question 2 - will I be able to compile for Open GL and still load 16bit texels
?

I am using a Real Yatty Engine Too
