* Bump API patch number and header version number to 36 for this update.
Github Issues:
* Fix "recorded with" terminology in the valid usage language for the
flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public
issue 390).
* Modify +genvk.py+ to support specifying extensions to remove from output
generators, allowing the extension loader +vulkan_ext.c+ to be created
without WSI extensions which are statically exported by the Vulkan
loader (public issue 412).
* Added validation language for slink:VkSubpassDependency and in the
<<synchronization-access-types-supported,supported access types>>
section to catch access masks that include bits which are not supported
by pipeline stages in the stage masks (partially addresses public issue
1006).
Internal Issues:
* Added validation language for flink:vkCmdWaitEvents,
flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the
<<synchronization-pipeline-stages-supported>> section to prevent
recording stage dependencies that aren't supported on the queue
(internal issue 516).
* Make a few changes that generalize spec language for use with possible
future extensions by adding glossary terms and generalizing ``feature''
to ``feature or extension'' where relevant (internal issues 448, 590).
* Added "pipeline type" attribute to +vk.xml+ for relevant commands and
utilize it in automatic generation of the Command Properties table
(internal issue 517).
* Specify that WSI implementations must provide both UNORM and sRGB
formats in the description of slink:VkColorSpaceKHR (internal issue
529).
* Remove nesting of explicit valid usage statements where it is not
meaningful (internal issue 583).
Other Issues:
* Add validity language requiring that
slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in
the spec language.

This extension allows an application to source the number of draw calls for
|
|
indirect draw calls from a buffer.
|
|
This enables applications to generate arbitrary amounts of draw commands and
|
|
execute them without host intervention.
