Delete Branch "Jeroen-Bakker/blender:vulkan/support-legacy-platforms"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Dynamic rendering is a Vulkan 1.3 feature. Most platforms have support
for them, but there are several legacy platforms that don't support dynamic
rendering or have driver bugs that don't allow us to use it.
This change will make dynamic rendering optional allowing legacy
platforms to use Vulkan.
Limitations
GPU_LOADACTION_CLEARis implemented as clear attachments.Render passes do support load clear, but adding support to it would
add complexity as it required multiple pipeline variations to support
suspend/resume rendering. It isn't clear when which variation should
be used what lead to compiling to many pipelines and branches in the
codebase. Using clear attachments doesn't require the complexity
for what is expected to be only used by platforms not supported by
the GPU vendors.
Subpass inputs and dual source blending are not supported as
Subpass inputs can alter the exact binding location of attachments.
Fixing this would add code complexity that is not used.
