docs: new Mesa source tree overview page.
This has been sitting around for a while. Incomplete, but a good start.

+<h1>Mesa source code tree overview</h1>
+
+<p>
+This is a brief summary of Mesa's directory tree and what's contained in
+each directory.
+</p>
+
+
+<ul>
+<li><b>docs</b> - Documentation
+<li><b>include</b> - Public OpenGL header files
+<li><b>src</b>
+ <ul>
+ <li><b>egl</b> - EGL library sources
+ <ul>
+ <li><b>docs</b> - EGL documentation
+ <li><b>drivers</b> - EGL drivers
+ <li><b>main</b> - main EGL library implementation. This is where all
+ the EGL API functions are implemented, like eglCreateContext().
+ </ul>
+ <li><b>mesa</b> - Main Mesa sources
+ <ul>
+ <li><b>glapi</b> - OpenGL API dispatch layer. This is where all the
+ GL entrypoints like glClear, glBegin, etc. are generated, as well as
+ the GL dispatch table. All GL function calls jump through the
+ dispatch table to functions found in main/.
+ <li><b>main</b> - The core Mesa code (mainly state management)
+ <li><b>drivers</b> - Mesa drivers (not used with Gallium)
+ <ul>
+ <li><b>common</b> - code which may be shared by all drivers
+ <li><b>dri</b> - Direct Rendering Infrastructure drivers
+ <ul>
+ <li><b>common</b> - code shared by all DRI drivers
+ <li><b>i915</b> - driver for Intel i915/i945
+ <li><b>i965</b> - driver for Intel i965
+ <li>XXX more
+ </ul>
+ <li><b>x11</b> - Xlib-based software driver
+ <li><b>osmesa</b> - off-screen software driver
+ <li><b>glslcompiler</b> - a stand-alone GLSL compiler driver
+ <li>XXX more
+ </ul>
+ <li><b>math</b> - vertex array translation and transformation code
+ (not used with Gallium)
+ <li><b>ppc</b> - Assembly code/optimizations for PPC systems
+ (not used with Gallium)
+ <li><b>shader</b> - Vertex/fragment shader and GLSL compiler code
+ <li><b>sparc</b> - Assembly code/optimizations for SPARC systems
+ (not used with Gallium)
+ <li><b>state_tracker</b> - State tracker / driver for Gallium. This
+ is basically a Mesa device driver that speaks to Gallium. This
+ directory may be moved to src/mesa/drivers/gallium at some point.
+ <li><b>swrast</b> - Software rasterization module. For drawing points,
+ lines, triangles, bitmaps, images, etc. in software.
+ (not used with Gallium)
+ <li><b>swrast_setup</b> - Software primitive setup. Does things like
+ polygon culling, glPolygonMode, polygon offset, etc.
+ (not used with Gallium)
+ <li><b>tnl</b> - Software vertex Transformation 'n Lighting.
+ (not used with Gallium)
+ <li><b>tnl_dd</b> - TNL code for device drivers.
+ (not used with Gallium)
+ <li><b>vbo</b> - Vertex Buffer Object code. All drawing with
+ glBegin/glEnd, glDrawArrays, display lists, etc. goes through this
+ module. The results is a well-defined set of vertex arrays which
+ are passed to the device driver (or tnl module) for rendering.
+ <li><b>vf</b> - vertex format conversion (currently unused)
+ <li><b>x86</b> - Assembly code/optimizations for 32-bit x86 systems
+ (not used with Gallium)
+ <li><b>x86-64</b> - Assembly code/optimizations for 64-bit x86 systems
+ (not used with Gallium)
+ </ul>
+ <li><b>gallium</b> - Gallium3D source code
+ <ul>
+ <li><b>include</b> - Gallium3D header files which define the Gallium3D
+ interfaces
+ <li><b>drivers</b> - Gallium3D device drivers
+ <ul>
+ <li><b>cell</b> - Driver for Cell processor.
+ <li><b>i915</b> - Driver for Intel i915/i945.
+ <li><b>i965</b> - Driver for Intel i965.
+ <li><b>llvmpipe</b> - Software driver using LLVM for runtime code generation.
+ <li><b>nv*</b> - Drivers for NVIDIA GPUs.
+ <li><b>r300</b> - Driver for ATI/AMD R300.
+ <li><b>softpipe</b> - Software reference driver.
+ <li><b>svga</b> - Driver for VMware's SVGA virtual GPU.
+ <li><b>trace</b> - Driver for tracing Gallium calls.
+ <li>XXX more
+ </ul>
+ <li><b>auxiliary</b> - Gallium support code
+ <ul>
+ <li><b>draw</b> - Software vertex processing and primitive assembly
+ module. This includes vertex program execution, clipping, culling
+ and optional stages for drawing wide lines, stippled lines,
+ polygon stippling, two-sided lighting, etc.
+ Intended for use by drivers for hardware that does not have
+ vertex shaders.
+ Geometry shaders will also be implemented in this module.
+ <li><b>cso_cache</b> - Constant State Objects Cache. Used to filter out
+ redundant state changes between state trackers and drivers.
+ <li><b>gallivm</b> - LLVM module for Gallium. For LLVM-based
+ compilation, optimization and code generation for TGSI shaders.
+ Incomplete.
+ <li><b>pipebuffer</b> - utility module for managing buffers
+ <li><b>rbug</b> - Gallium remote debug utility
+ <li><b>rtasm</b> - run-time assembly/machine code generation.
+ Currently there's run-time code generation for x86/SSE, PowerPC
+ and Cell SPU.
+ <li><b>tgsi</b> - TG Shader Infrastructure. Code for encoding,
+ manipulating and interpretting GPU programs.
+ <li><b>translate</b> - module for translating vertex data from one format
+ to another.
+ <li><b>util</b> - assorted utilities for arithmetic, hashing, surface
+ creation, memory management, 2D blitting, simple rendering, etc.
