/**
 * A pool of geometry buffers tied to a GrGpu.
 *
 * The pool allows a client to make space for geometry and then put back excess
 * space if it over allocated. When a client is ready to draw from the pool
 * it calls unmap on the pool ensure buffers are ready for drawing. The pool
 * can be reset after drawing is completed to recycle space.
 *
 * At creation time a minimum per-buffer size can be specified. Additionally,
 * a number of buffers to preallocate can be specified. These will
 * be allocated at the min size and kept around until the pool is destroyed.
