BufferManager
Direct Subclass:
BufferManager keeps track of (CPU side) buffers, these buffers are eventually flushed to the GPU.
This class should be considered abstract. It contains all code that is shared by the implementations:
- BufferManagerPerColor (keeps a buffer alive per unique color)
BufferManagerTransparencyOnly (keeps two buffers alive, one for opaque objects and one for transparent)
Because of allocation costs, buffers are reused. Flushed buffers will reset their indices (resetBuffer), subsequently overwriting old data.
