From 5457e58a64b0aba808a055d72610c5ba856a4f09 Mon Sep 17 00:00:00 2001 From: Danylo Piliaiev Date: Mon, 18 Jun 2018 15:50:57 +0300 Subject: i965: Advertise 8 bits subpixel precision for viewport bounds on gen6+ We use floating-points for viewport bounds so VIEWPORT_SUBPIXEL_BITS should reflect this.
