Public Member Functions
void	reset ()
	Clears usage counters and the sticky rejection state for a new frame.
bool	reserve (int width, int height, std::size_t surfaceCount=1, std::uint64_t bytesPerPixel=4)
	Reserves matching surfaces; invalid dimensions or exhausted capacity latch rejection.
bool	canReserveBytes (std::uint64_t bytes, std::size_t surfaces) const
	Tests additional capacity without changing counters or latching a rejection.
bool	release (int width, int height, std::size_t surfaceCount=1, std::uint64_t bytesPerPixel=4)
	Releases surfaces after their last submitted GPU use, restoring active-capacity accounting.
std::uint64_t	bytes () const
	Bytes currently reserved by active surfaces.
std::size_t	surfaces () const
	Number of active reserved surfaces.
bool	rejected () const
	Whether a reservation or release has failed in this frame.
void	setLimitsForTesting (Limits limits)
	Tightens limits for a test without raising an existing limit.

Static Public Attributes
static constexpr std::uint64_t	kMaximumBytes = 256ULL * 1024 * 1024
	Default upper bound on aggregate surface storage.
static constexpr std::size_t	kMaximumSurfaces = 256
	Default upper bound on concurrently reserved surfaces.
