Detailed Description

Linear allocator for temporary device local buffer allocations.

Linear allocator uses linear allocation strategy. It places allocated buffers sequentially in a large pre-allocated arena buffer. If arena is full, new arena allocated. On a free all step, all allocations must be invalid. All allocated arenas cleared, and one new bigger arena allocated.
