[arch-general] is mesa, glproto, dri2proto not needed by intel video driver anymore?

[Thanos Zygouris]

Hi,
If i run 'pacman -Qdt' (search for not needed installed packages) i got:
dri2proto 2.8-1
glproto 1.4.16-1
mesa 9.0-1

If i remember right, these were intalled by xf86-video-intel, or
intel-dri in the past.
So, my question is: can i remove these packages safely?

My video card is:
'Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller'
and i am using intel driver, with KMS (i915).
