Since we are only cleaning up objects that haven't been used in the
last 5000 frames, we do not need to wait to delete them.

For systems where VK_EXT_extended_dynamic_state is not supported
it is not valid to extend VkDeviceCreateInfo with an unknown struct.
Todo: if more extensions are supported in the future this code probably
needs adjustments to correctly build a pNext chain.

Sometimes no buffer for tex coords are given, however the shader
still expects some. We can fix this by using a default buffer, which
contains the constant tex coords (0, 0), which is then bound instead.

Some implementations allow for bottomless pools,
which never run out of pool memory.
This new implementation allows for this case to happen.
