// This class lets calculators allocate GpuBuffers of various sizes, caching
|
|
// and reusing them as needed. It does so by automatically creating and using
|
|
// platform-specific buffer pools for the requested sizes.
|
|
//
|
|
// This class is not meant to be used directly by calculators, but is instead
|
|
// used by GlCalculatorHelper to allocate buffers.
