class UniformBufferPool
Defined at line 24 of file ../../src/ui/lib/escher/impl/uniform_buffer_pool.h
Vends host-accessible Buffers whose resources are automatically returned
to the pool upon destruction. If necessary, it will grow by creating new
buffers (and allocating backing memory for them). |additional_flags| allows
the user to customize the memory that is allocated by the pool; by default,
only eHostVisible is used. Not thread-safe.

BufferPtr Allocate ()Allocate a buffer that will be returned to this pool when the last
reference to it is dropped.

vk::DeviceSize buffer_size ()Return the size of buffers allocated by this allocator; constant over the
allocator's lifetime.
NOTE: this value is currently always 64kB, which is a typical max-size for
Vulkan uniform buffers.

void BeginFrame ()Rotate the ring buffer so that buffers freed in previous frames are moved
toward the front.
