From: Józef Kucia Date: Tue, 19 Jul 2016 11:07:24 +0000 (+0200) Subject: gallium: add a cap for VIEWPORT_SUBPIXEL_BITS (v2) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3cd28fe3de203934f2bab33cce7a91da499c7376;p=mesa.git gallium: add a cap for VIEWPORT_SUBPIXEL_BITS (v2) This allows Gallium drivers to advertise the subpixel precision for floating point viewports bounds. v2: - Set ViewportSubpixelBits in st_init_limits.
