[Mesa3d-dev] Mesa 3.3 defaults to 24bit Zbuffer for Voodoo2 ??

[<ant...@wm...>]

While I am trying to figure out why 3.3 does not work with Q3demo (but
works w/ Q3test or SOF, but for some reason the top 40-80 scan lines are
cut off.. that's another weird thing.. maybe because I have X4.0.1 ?)
I stumbled accross this weirdness:

with all the Mesa's that come w/ Q3test and Q3Demo and Q3A they will
default at 640x480x16bit colordepth and 16bit Zbuffer on my Voodoo2.

For some reason when I use 3.3 with Q3test and Q3demo (before it crashes) 
they report that they have a 24bit Zbuffer!?  Now maybe i am confused, but
doesn't the Voodoo2 have a maximum of 16bit zbuffer (either integer and
floating point? I think that's what Gary Tarolli told me)


Another problem I noticed is that the FXMesa module is version 0.30 but it
does not detect (or at least report) the right settings for my Voodoo2:

One of the old ones:
GL_VENDOR: Brian Paul
Mesa CVA Extension (C) 1999 Keith Whitwell
GL_RENDERER: Mesa Glide v0.30 Voodoo_Graphics 0 CARD/4 FB/4 TM/2 TMU/NOSLI
GL_VERSION: 1.2 Mesa 3.1 beta


as opposed to the new one:

GL_VENDOR: Brian Paul
GL_RENDERER: Mesa Glide v0.30 Voodoo_Graphics 0 CARD/0 FB/0 TM/2 TMU/NOSLI
GL_VERSION: 1.2 Mesa 3.3

0mb of Framebuffer? 2Mb of texture memory?  At least it got my 2TMU's
right. It obviously works ok, but I am wondering why it does this?
