Subject: st/nine: Reduce MaxSimultaneousTextures to 8
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d975e98e4abac853fcbb35dbb1537d2069d5125;p=mesa.git

st/nine: Reduce MaxSimultaneousTextures to 8

Windows drivers don't set this flag (which affects ff) to more than 8.

Do the same in case some games check for 8.

v2: Remove any dependence on MaxSimultaneousTextures. For non-ff
the number of textures is 16 when the device is able of vs/ps3.
Add this requirement of 16 textures to the driver requirements.
