Subject: mesa/formats: add rest of integer formats.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7a41291c3aa13fc71cc87966b414551f5c7c0e6a;p=mesa.git

mesa/formats: add rest of integer formats.

This is taken from reading EXT_texture_integer + EXT_texture_rg in combination,

Comments on necessity of each format, naming of formats and bugs in the
formats tables please.

Is there any formats I've missed?

Eric looked over this to make sure its consistent at least.

As I've changed the ordering of things in the format table, the follow
patches are required to avoid regression.
