Author: Neil Roberts <[email protected]> Date: Mon Jun 22 09:49:33 2020 +0200 nir: Add intrinsics for the line width The first intrinsic is intended to expose the value set by glLineWidth to shaders internally. The second intrinsic exposes the value actually sent to the hardware. This may be wider than the first one in order to implement anti-aliasing. These will be used in later patches to implement a line smoothing lowering pass. v2: Add a second intrinsic for the expanded line width for anti-aliasing.
