[virglrenderer-devel] [PATCH 3/7] shader: add image support to shader parsing.
Dave Airlie
airlied at gmail.com
Fri Jul 20 00:05:10 UTC 2018
From: Dave Airlie <airlied at redhat.com>
This converts the image related opcodes, and tracks the used
images.
Images need some extensions for extra features:
ES_3_1_compatability is needed for r32f image support
shader_image_size for image size support
