// The compile-time link between AnimationShaderContract::kMaxUserTextureSlots
// and PhosphorRendering::kMaxUserTextures lives in
// libs/phosphor-animation/src/contract_pins.cpp. It cannot live in this header
// because translation units that only need contract definitions (notably the
// kwin-effect, which already pulls in epoxy/gl.h via KWin) must not be forced
// to also pull in <QtQuick/QSGTextureProvider> via ShaderNodeRhi.h — epoxy and
// Qt's qopenglext.h declare overlapping GL function-pointer typedefs that
// conflict when both end up in the same TU.
