Hi Performers,

I think that what I'm trying to do is not possible. I'd like experienced people
to tell me if I'm wrong...

I want to generate textures on the fly in my app. These textures are then
loaded into TRAM using the PFTEX_SOURCE_FRAMEBUFFER load mode (thanks Anita
btw:-)

1) Ideally, the generated textures should not be visible so they should be
rendered off-screen.
Yet, from what I understand it is not possible to render something off-screen
using hardware acceleration, right?

2) The textures should be transparent. This means I must specify a format like:
    pfTexFormat(tex, PFTEX_INTERNAL_FORMAT, PFTEX_RGBA_8);
But in this case what does the "A" refer to? To the Z-buffer in the FB?

Any comments appreciated,

Amaury.
