Subject: gallium: add PIPE_CAP_VIEWPORT_TRANSFORM_LOWERED
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This new capability indicates that the nir_lower_viewport_transform
pass is enabled. This also means that the gl_Position value is
modified and should be lowered for transform feedback, if needed.
