+
+NOTE:
+
+These files are incomplete. They do not yet form a working
+implementation of hte concepts discused below.
+
+
+OVERVIEW
+
+The t_dd_imm_* files form a set of templates to produce driver -
+specific software tnl modules for a small subset of transformation and
+lighting states.
+
+The approach is quite different to the large vertex buffers of the
+src/tnl module, and is based around a cache of four recent vertices
+and a 'current' vertex which is updated directly from the Color,
+Normal, Texcoord, SecondaryColor and Fog entrypoints.
+
+The current vertex is actually a composite of the ctx->Current values
+and a partial hardware vertex maintained where the hardware values
+differ from those in ctx->Current. For example, clamped color values
+are kept in the hardware vertex, while texcoords remain in
+ctx->Current.
+
+A crude diagram:
+
+ +--------------+ +-------------------+
+ | ctx->Current | | Current-HW-vertex |
+ +--------------+ +-------------------+
+ \ /
+ \ /
+ \ /
+ \ /
+ --------- --------
+ | |
+ v v
+ +--------+ +--------+ +--------+ +--------+
+ | vert-0 | | vert-1 | | vert-2 | | vert-3 |
+ +--------+ +--------+ +--------+ +--------+
+ |
+ |
+ v
+
+ DMA
+
+
+Here values from ctx->Current and current-HW-vertex are merged to
+build vert-2, which is then dumped to hardware (DMA). A state machine
+determines which vertex is built in turn, and how the vertices are
+used to present primitives to hardware. These actions all occur
+during a call to Vertex{234}f{v}.
+
+Each vert-n includes clip coordinates and a clipmask in addition to
+the hardware (window) coordinates. This information allows clipping
+to take place directly on these vertices, if need be.
+
+t_dd_imm_capi.h
+
+ Color{34}{fub}{v}() implementations. These update both
+ ctx->Current (unclamped float colors) and current-HW-vertex
+ with hardware-specific color values (typically unsigned
+ bytes).
+
+ When lighting is enabled, the functions from src/api_noop.c
+ should be used, which just update ctx->Current. (The
+ current-hw-vertex colors are produced from lighting, which is
+ keyed to Normal3f).
+
+t_dd_imm_vb.c
+
+ Support functions for clipping and fallback. See
+ t_dd_imm_primtmp.h.
+
+t_dd_imm_napi.c
+t_dd_imm_napi.h
+
+ Versions of Normal3f{v} to perform lighting with one or more
+ infinite lights. Updates ctx->Current.Normal and the current
+ HW colors.
+
+ When lighting is disabled, use the functions from api_noop.c
+ instead.
+
+
+t_dd_imm_primtmp.h
+
+ State machine to control emission of vertices and primitives
+ to hardware. Called indirectly from Vertex{234}f{v}. Capable
+ of supporting hardware strip and fan primitives, and of
+ decomposing to discreet primitives for clipping or fallback,
+ or where the native primitive is unavailable.
+
+t_dd_imm_tapi.h
+
+ Implementations of TexCoord{v} and MultiTexCoord4f{v}ARB to
+ fire a callback when transitioning to projective texture.
+ Most drivers will need to change vertex format at this point,
+ some may need to enable a software rasterization fallback.
+
+t_dd_imm_vapi.h
+
+ Implementations of Vertex{234}f{v}. These perform
+ transformation and cliptesting on their arguments, then jump
+ into the state machine implemented in primtmp.h.
+
+t_dd_imm_vertex.h
+
+ Support functions for building and clip-interpolating hardware
+ vertices. Called from primtmp.h.
