 188     *
 189     * We could implement this by walking over all of the attachments and

 191     * dependency.  Or, we could just be lazy and add a couple extra flushes.
 192     * We choose to be lazy.
 193     *
 194     * From the documentation for vkCmdNextSubpass:
 195     *
 196     *    "Moving to the next subpass automatically performs any multisample
 197     *    resolve operations in the subpass being ended. End-of-subpass
 198     *    multisample resolves are treated as color attachment writes for the
 199     *    purposes of synchronization. This applies to resolve operations for
 200     *    both color and depth/stencil attachments. That is, they are
 201     *    considered to execute in the
 202     *    VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT pipeline stage and
 203     *    their writes are synchronized with
 204     *    VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT."
 205     *
 206     * Therefore, the above flags concerning color attachments also apply to
 207     * color and depth/stencil resolve attachments.
