* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).

This extension adds support for an exclusive scissor test to Vulkan.
|
|
The exclusive scissor test behaves like the scissor test, except that the
|
|
exclusive scissor test fails for pixels inside the corresponding rectangle
|
|
and passes for pixels outside the rectangle.
|
|
If the same rectangle is used for both the scissor and exclusive scissor
|
|
tests, the exclusive scissor test will pass if and only if the scissor test
|
|
fails.

=== Issues
|
|
|
|
1) For the scissor test, the viewport state must be created with a matching
|
|
number of scissor and viewport rectangles.
|
|
Should we have the same requirement for exclusive scissors?
|
|
|
|
*RESOLVED*: For exclusive scissors, we relax this requirement and allow an
|
|
exclusive scissor rectangle count that is either zero or equal to the number
|
|
of viewport rectangles.
|
|
If you pass in an exclusive scissor count of zero, the exclusive scissor
|
|
test is treated as disabled.
