--
-- == Description
--
-- This extension allows the execution of one or more rendering commands to
-- be conditional on a value in buffer memory. This may help an application
-- reduce the latency by conditionally discarding rendering commands
-- without application intervention. The conditional rendering commands are
-- limited to draws, compute dispatches and clearing attachments within a
-- conditional rendering block.
--
-- == New Commands
--
-- -   'cmdBeginConditionalRenderingEXT'
--
-- -   'cmdEndConditionalRenderingEXT'
--
-- == New Structures
--
-- -   'ConditionalRenderingBeginInfoEXT'
--
-- -   Extending
--     'Vulkan.Core10.CommandBuffer.CommandBufferInheritanceInfo':
--
--     -   'CommandBufferInheritanceConditionalRenderingInfoEXT'
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceConditionalRenderingFeaturesEXT'
--
-- == New Enums
--
-- -   'ConditionalRenderingFlagBitsEXT'
--
-- == New Bitmasks
--
-- -   'ConditionalRenderingFlagsEXT'
--
-- == New Enum Constants
--
-- -   'EXT_CONDITIONAL_RENDERING_EXTENSION_NAME'
--
-- -   'EXT_CONDITIONAL_RENDERING_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.AccessFlagBits.AccessFlagBits':
--
--     -   'Vulkan.Core10.Enums.AccessFlagBits.ACCESS_CONDITIONAL_RENDERING_READ_BIT_EXT'
--
-- -   Extending
--     'Vulkan.Core10.Enums.BufferUsageFlagBits.BufferUsageFlagBits':
--
--     -   'Vulkan.Core10.Enums.BufferUsageFlagBits.BUFFER_USAGE_CONDITIONAL_RENDERING_BIT_EXT'
--
-- -   Extending
--     'Vulkan.Core10.Enums.PipelineStageFlagBits.PipelineStageFlagBits':
--
--     -   'Vulkan.Core10.Enums.PipelineStageFlagBits.PIPELINE_STAGE_CONDITIONAL_RENDERING_BIT_EXT'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_COMMAND_BUFFER_INHERITANCE_CONDITIONAL_RENDERING_INFO_EXT'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_CONDITIONAL_RENDERING_BEGIN_INFO_EXT'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_CONDITIONAL_RENDERING_FEATURES_EXT'
--
-- == Issues
--
-- 1) Should conditional rendering affect copy and blit commands?
--
-- __RESOLVED__: Conditional rendering should not affect copies and blits.
--
-- 2) Should secondary command buffers be allowed to execute while
-- conditional rendering is active in the primary command buffer?
--
-- __RESOLVED__: The rendering commands in secondary command buffer will be
-- affected by an active conditional rendering in primary command buffer if
-- the @conditionalRenderingEnable@ is set to
-- 'Vulkan.Core10.FundamentalTypes.TRUE'. Conditional rendering /must/ not
-- be active in the primary command buffer if @conditionalRenderingEnable@
-- is 'Vulkan.Core10.FundamentalTypes.FALSE'.
--
-- == Examples
--
-- None.
--
-- == Version History
--
-- -   Revision 1, 2018-04-19 (Vikram Kushwaha)
--
--     -   First Version
--
-- -   Revision 2, 2018-05-21 (Vikram Kushwaha)
--
--     -   Add new pipeline stage, access flags and limit conditional
--         rendering to a subpass or entire render pass.
