Namespaces
namespace	PhosphorShaders
namespace	PhosphorShaders::CustomParams
	Canonical key format for the customParams[N].
namespace	PhosphorShaders::CustomColors
	Canonical key format for the customColors[N] slots in BaseUniforms.

Functions
bool	PhosphorShaders::isValidWrapToken (const QString &wrap)
	The accepted texture / buffer wrap vocabulary, shared by every validation site across the shader registries (overlay image-param parse, surface metadata parse, per-slot texture parse, and runtime override translation).
bool	PhosphorShaders::isValidFilterToken (const QString &filter)
	The accepted buffer filter vocabulary: linear / nearest / mipmap.
QString	PhosphorShaders::CustomParams::slotKey (int vec, char comp)
	Format a customParams slot key from explicit (vec, comp) pair.
QString	PhosphorShaders::CustomParams::slotKey (int slot)
	Format a customParams slot key from a flat sub-slot index in [0, kFlatSlotCount).
QString	PhosphorShaders::CustomParams::glslAccessor (int slot)
	GLSL author-facing accessor for a flat scalar sub-slot — the form a shader author reads in fragment source, as opposed to slotKey()'s QVariantMap serialisation form.
QString	PhosphorShaders::CustomColors::colorKey (int slot)
	Format a customColor key from a 0-based slot index.
QString	PhosphorShaders::CustomColors::glslAccessor (int slot)
	GLSL author-facing accessor for a color slot — the form a shader author reads in fragment source, as opposed to colorKey()'s QVariantMap serialisation form.

Variables
constexpr double	PhosphorShaders::kMinBufferScale = 0.125
	Lower / upper bounds on a multipass bufferScale (FBO downscale factor).
constexpr double	PhosphorShaders::kMaxBufferScale = 1.0
constexpr int	PhosphorShaders::kMaxBufferPasses = 4
	Maximum number of multipass buffer passes a pack may declare.
constexpr int	PhosphorShaders::CustomParams::kVecCount = 8
	Number of vec4 slots in BaseUniforms::customParams[8].
constexpr int	PhosphorShaders::CustomParams::kFlatSlotCount = 4 * kVecCount
	Number of float sub-slots across all vec4s (4 × kVecCount).
constexpr int	PhosphorShaders::CustomColors::kColorCount = 16
	Number of color slots in BaseUniforms::customColors[16].
