The DelayedDeletionQueue is a general utility for queueing up things to delete at a future time.
This simplifies swapchain recreation by making the deletion of in-use objects to be done later when they are no longer in use.
The SwapchainManager handles all aspects of a swapchain:
* Creation - Pass a SwapchainBuilder to specify how the swapchain should be created.
* Recreation - Recreates the swapchain without introducing a pipeline stall through the use of an internal DelayedDeletionQueue.
* Semaphores - Handles setting up the semaphores for acquiring a swapchain image, submitting work to draw to it, then presenting it.
* Fences - Owns the fences associated with the command buffer submissions which write to the swapchain image.
Optionally, the SwapchainManager can also provide command buffers in which to record with for ease of use in simple situations.
There is a ImagelessFramebufferBuilder to simplify creating imageless framebuffers into a few lines of code. Nothing special,
but is a nice thing to have
Also in these changes
Fixed issue with image usage flags inheriting the wrong flags and causing validation message spam.
The example triangle now will have a absolute filepath to the shaders.
This allows running the exe from directories other than the location of the shaders in the filesystem.
Alternative solutions would be to copy/paste the shader binary into the source code.
find_package is used to try to find the Vulkan-Headers, and if they aren't
present, it downloads them with fetch content. This way users don't need
vulkan 'installed' on their system, specifically for windows users.
It also changes the tests to load all the necessary function pointers, that
way we don't need to find the vulkan loader to build the tests.
To recreate a swapchain now requires making a new SwapchainBuilder or
keeping the old one around. Removed the recreate function since its
purpose was unclear. Introduced set_old_swapchain to allow recyling the
old swapchain. Updated documentation and getting started guide.
Updated the documentation for using the new <error_code> based errors.
Also fixed an issue where SystemInfo wouldn't check if layers had a
debug_utils extension.
Added device::get_queue_families() to facilitate custom queue setups
get_swapchain_images() renamed to get_image(), made member function to
swapchain.
get_swapchain_image_views() renamed to get_image_views(), also moved to
member function of swapchain
fixed bug with headless instance not being correct
Stopped Catch2 from polluting the buildable targets
SystemInfo will be the way for users to know what is and isn't available on their system.
Currently, it only has booleans for if validation layers and debug messenger are available,
but more could be added in the future.
Premise is to let the easy creation of a compute or transfer queue.
If the user supplies a custom list they want to use, defer to that.
Else, enable the basic requirements and be on your merry way.
