[Mesa-dev] [PATCH] anv: Sanitize Image extents and offsets
Nanley Chery
nanleychery at gmail.com
Thu Mar 24 16:27:02 UTC 2016
From: Nanley Chery <nanley.g.chery at intel.com>
Prepare Image extents and offsets for internal consumption by assigning
the default values implicitly defined by the spec. Fixes textures on
several Vulkan demos in which the VkImageCopy depth is set to zero when
copying a 2D image.
