Dynamic
class DynamicGpuBufferWriter @JvmOverloads constructor(val label: String, val usage: Int, val growPolicy: DynamicGpuBufferWriter.GrowPolicy = GrowPolicy.DEFAULT) : AutoCloseable
Per-frame dynamic com.mojang.blaze3d.buffers.GpuBuffer writer for streaming VBO/IBO uploads.
Follows vanilla's net.minecraft.client.renderer.StagedVertexBuffer pattern: CPU data is written to a properly-flagged GPU buffer via com.mojang.blaze3d.systems.CommandEncoder.writeToBuffer, which performs an immediate DMA copy without mapping. Buffers are recycled via fence when the GPU has finished consuming them.
Unlike net.minecraft.client.renderer.MappableRingBuffer, this class does not use persistent mapping, avoiding the fence issue of wrapping within a single command encoder submit.
Lifecycle
upload: acquire/write data (auto-grows buffer as needed)
endFrame: fence the current buffer for recycling
