void	countTextureWrite (uint64_t bytes) const
	Forwards to GeodeDevice::countTextureWrite when wired.
void	countSubmit () const
	Forwards to GeodeDevice::countSubmit when wired.
GeodeMaskPipeline &	maskPipeline () const
	The Slug mask pipeline: maskPipelineOverride when set (tests), otherwise the shared lazily-built GeodeDevice::maskPipeline(). Requires one of the two to be available.

Public Attributes
gpu::Device *	gpuDevice = nullptr
	The GPU runtime device recording is performed against. Required (never null when wired).
GeodeDevice *	geodeDevice = nullptr
	Optional counter sink + lazy mask-pipeline owner. Null in GPU-less test harnesses.
const gpu::TextureView *	dummyPatternTextureView = nullptr
	1x1 opaque-black RGBA8 dummy view bound into the pattern slot of solid / gradient draws.
const gpu::Sampler *	dummyPatternSampler = nullptr
	Linear-Repeat sampler paired with dummyPatternTextureView (and real pattern tiles).
const gpu::TextureView *	dummyClipMaskTextureView = nullptr
	1x1 full-coverage dummy view bound into the clip-mask slot when no clip mask is active.
const gpu::Sampler *	dummyClipMaskSampler = nullptr
	Linear-ClampToEdge sampler paired with dummyClipMaskTextureView (and real masks).
const gpu::Buffer *	identityInstanceRecordBuffer = nullptr
	One full-size identity instance record, bound by every non-instanced Slug fill.
const gpu::Buffer *	dummyPaintDataBuffer = nullptr
	One zero-filled gradient paint block, bound by draws that carry no gradient paint.
GeodeMaskPipeline *	maskPipelineOverride = nullptr
	Test override for maskPipeline. Production leaves this null and resolves the shared lazily-built pipeline through geodeDevice.

Detailed Description

Everything Geode's encoders need to record a frame through the donner::gpu runtime.

Production wires one of these from GeodeDevice (see GeodeDevice::gpuContext()): the gpuDevice is the device's adapter, the dummy resources are the shared device-owned identity fills for inactive pattern / clip-mask / paint bind slots, and the counter helpers forward to the GeodeDevice perf counters. A test harness can instead construct one against a GPU-less donner::gpu::Device with geodeDevice == nullptr (counters become no-ops) and maskPipelineOverride set.

Non-owning: every pointer references state owned by the wiring scope, which must outlive any encoder recording against this context.
