[RESEND xserver 0/1] glx: Always enable EXT_texture_from_pixmap for DRI glx

[Hans de Goede]

Hi All,

I know that when this was sent before it was not liked because things
should really be fixed in Mesa, but in the mean time no-one has
stepped up and fixed Mesa.

Without this patch 1.19 will regress users who rely on llvmpipe, e.g.
people running gnome as desktop in VMs, so I believe that we should
add this patch to 1.19 as it is much too late to rely on / expect a
Mesa fix now.

Regards,

Hans
