Variables
constexpr std::uint32_t	open3d::visualization::rendering::kGaussianGpuErrorTileEntryOverflow = 1u << 0
	Set when the shared sort-entry buffer overflows (total entries > capacity).
constexpr std::uint32_t	open3d::visualization::rendering::kGaussianGpuErrorSortCountClamped = 1u << 1
	Set when the radix-sort dispatch count is clamped to the entry capacity.
