Description
This extension incorporates VK_ATTACHMENT_STORE_OP_NONE_EXT from
VK_QCOM_render_pass_store_ops, enabling applications to avoid
unnecessary synchronization when an attachment is not written during a
render pass.
Additionally, VK_ATTACHMENT_LOAD_OP_NONE_EXT is introduced to avoid
unnecessary synchronization when an attachment is not used during a render
pass at all.
In combination with VK_ATTACHMENT_STORE_OP_NONE_EXT, this is useful as
an alternative to preserve attachments in applications that cannot decide if
an attachment will be used in a render pass until after the necessary
pipelines have been created.
