Isn't this technically incorrect when the uploaded texture is integer?
To be honest, it's not really clear to me what the return type is supposed
to mean. I don't think any of the hardware drivers uses it.
Adreno has different texture instructions depending on the desired
return type. If you use a float return type on an int texture, you
will get a floating point value of that integer (i.e. if the actual
textured value were 100, you'd get 100.0f returned if you did
sam.f32).
I guess this mean PBO uploads of integer textures is currently broken
for Adreno?
