Users can now ask for physical devices which support a specific 1.1 and 1.2
feature. VkBootstrap will then add the selected features to the enable list
in device creation.
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.
This commit removes the many casts from int to uint and back, as -1 was used
as a sentinel value. Because thats confusing and leads to many casts
everywhere it was decided to add a sentinel value and compare everything
to that to determine if a queue index is valid or not.
Making the destroy_messenger public allows code to store the handle directly and
delete it themselves instead of having to hold onto a vkb::Instance, which requires
including the header.
Allows people to use Swapchain Builder withtout holding onto the vkb::Device
handle. Also made patch levels optional since they generally don't matter.
Make vk-bootstrap capable of loading the vulkan runtime and not need to
link against the library. This improves the usability of vk-bootstrap since
now you don't need the vulkan library on your system to build.
This commit also changes how SystemInfo works so as to allow the dynamic
vulkan loading.
Delete .gitmodules, update readme to mention that enabling testing
automatically gets the dependencies, no more git submodules.
Add license to top of source files.
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.
Previously, on linux all three windowing extensions would be added
(xcb, xlib, wayland) even if they weren't available.
Now, InstanceBuilder first makes sure they are present before
adding them.
Also added a new error code to represent the lack of wsi extensions
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.
