ensure_buffer_capacity()

void MayaFlux::Buffers::DescriptorBindingsProcessor::ensure_buffer_capacity ( DescriptorBinding &  binding, size_t  required_size  )

private

Ensure descriptor buffer has sufficient capacity.

Parameters

binding	Descriptor binding to check
required_size	Minimum required size in bytes

If buffer is too small, resizes with 50% over-allocation. Sets m_needs_descriptor_rebuild flag if resize occurs.
