v0.7.0

Major features

• Add first-class support for VK_KHR_acceleration_structure
• Add first-class support for VK_KHR_ray_tracing_pipeline

• Implement the log-objects feature to log all vkCreate... and vkDestroy... calls
• Major simplifications to library initialization with helper methods.

Changes

Breaking

• Extract pass executor type into a trait
• Rename PassBuilder::execute to PassBuilder::execute_fn, the old method still exists but now takes any PassExecutor instead of a function type.
• Pass executors now get a mutable reference to some user data passed in at record time
• Simplify lifetime of pass executor callback
• PipelineCache now takes an Allocator to construct (this is necessary to create a shader binding table for RT pipelines).

Non breaking

• Add resolve_and_bind_storage_image to command buffer
• Add write_storage_image and read_storage_image to pass builder
• Implement Send and Sync for PipelineCache
• Add IncompleteCommandBuffer::push_constant to upload a single value instead of a slice
