ensure_staging()

void MayaFlux::Buffers::NetworkGeometryProcessor::ensure_staging ( NetworkBinding &  binding, size_t  bytes  )

private

Grow a binding's staging buffer to hold at least bytes.

The target vertex buffer resizes with 1.5x headroom when a network grows, so the staging buffer it was sized against goes stale. Growing by the same factor keeps reallocation proportional to growth rather than per frame.

Parameters

binding	Binding whose staging_buffer is checked and possibly replaced.
bytes	Required capacity.
