nCine::RHI::LegacyGL namespace

Fixed-function OpenGL 1.x backend, selected by WITH_RHI_LEGACYGL.

The one member of this family that is not a console: its target is an OpenGL with no programmable stage at all — MorphOS' TinyGL (see Hardware rendering through TinyGL), and a desktop GL in a compatibility context, which is where that path is developed. It consumes nCine::RHI::FixedFunctionPass like the console backends, with each TEV preset expressed as an OpenGL 1.3 GL_COMBINE program.

Namespaces

namespace UniformTypeInfo: Free-function helpers that classify reflected uniform types (component count, float-ness).
