+=== Short Description

+Enables tighter array and struct packing to be used with uniform buffers.
+
+=== Description
+
+This extension modifies the alignment rules for uniform buffers, allowing
+for tighter packing of arrays and structures.
+This allows, for example, the std430 layout, as defined in
+https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.4.60.pdf[GLSL]
+to be supported in uniform buffers.

+
+When using a framebuffer with mixed samples, a per-fragment coverage
+reduction operation is performed which generates a color sample mask from
+the coverage mask.
+This extension defines the following modes to control how this reduction is
+performed.
+
+  * Merge: When there are more raster samples than color samples, there is
+    an implementation dependent association of each raster sample to a color
+    sample.
+    In the merge mode, the reduced color sample mask is computed such that
+    the bit for each color sample is 1 if any of the associated bits in the
+    fragment’s coverage is on, and 0 otherwise.
+    This is the default mode.
+
+  * Truncate: When there are more raster samples (N) than color samples(M),
+    there is one to one association of the first M raster samples to the M
+    color samples and the coverage bits for the other raster samples are
+    ignored.
+
+When the number of raster samples is equal to the color samples, there is a
+one to one mapping between them in either of the above modes.
+
+The new command
+flink:vkGetPhysicalDeviceSupportedFramebufferMixedSamplesCombinationsNV can
+be used to query the various raster, color, depth/stencil sample count and
+reduction mode combinations that are supported by the implementation.
+This extension would allow an implementation to support the behavior of both
+`VK_NV_framebuffer_mixed_samples` and `VK_AMD_mixed_attachment_samples`
+extensions simultaneously.

+== New Flags and Bitmask Types
+
+When an extension introduces a new flags (etext:*Flags) type, it should also
+introduce a corresponding new bitmask (etext:*FlagBits) type.
+The flags type contains zero more more bits from the bitmask, and is used to
+specify sets of bits for commands or structures.
+
+In some cases, a new flags type will be defined with no individual bits yet
+specified.
+This usage occurs when the flags are intended for future expansion.
+In this case, even though the corresponding bitmask type is not yet useful,
+the (empty) bitmask type should be defined in `vk.xml`.
+The empty bitmask type and corresponding flags type should be given
+boilerplate definitions in the specification.
