I'm trying to use the AUX buffers for offscreen rendering, but the picture
on the screen still changes. Also, even when not trying to write into some AUX buffer
I can still read from it and get the picture which shows on the screen. I'm using Mesa-3.4.1 on
a Solaris machine. Does it means that these buffers are not implemented in Mesa?
Are these buffers implemented only in hardware or am I doing something wrong?
I'm using glDrawBuffer(GL_AUX0) to direct the rendering to AUX0 and not the screen
and glReadBuffer, glReadPixels to read the date.
