azur: double buffer space for command data 
Now that it's in the main RAM we don't have to limit it as much.

meta: new build system (and emscripten fullscreen) 
* Update the build system to support intermediate installs (instead of
  exposing CMake targets that were only usable from within the main
  CMakeLists.txt).
* Finish the emscripten build and add detailed instructions in
  README.md.
* Get rid of runtime GLSL files by embedding them into a C file. This
  solves the annoying problem of where to install them and how to find
  them at runtime.
* Provide FindAzur.cmake to access the library. At the moment the module
  still needs to be found which requires a set(CMAKE_MODULE_PATH) in
  user applications. I consider this an acceptable compromise.
* Automatically go soft-fullscreen in the emscripten application.

azur: replace P8 with P8_RGB565A (4.5 c/p), P8_RGB565 (3 c/p) 
The code for P8 failed in some non-transparent cases and I'll admit I
could not be bothered to fix it when the superiors formats were already
designed and promised a significant boost.

meta: build system for Dear ImGui + GL3W + FreeType2 
* Add build instructions for Dear ImGui that build the SDL +
  OpenGL 3 / OpenGL ES 2 backend.
* Use Dear ImGui's bundled GL3W as a loader (including in azur itself,
  which has not been using a loader until now).
* Properly select headers for OpenGL ES 2.0 (with the VAO extension) and
  attributes for WebGL; clear up OpenGL 4 error codes.
* If FreeType2 is available through pkg-config, or if empscripten is
  used (since it has a FreeType port), use FreeType to render fonts in
  Dear ImGui for much-appreciated hinting quality.

Minor changes:
* Add window title to azur_init().
* Use emscripten's infinite loop simulation to make sure everything
  stays in the same thread. This is needed for Dear ImGui to work.

Lephe 3a3f607303 azur: basic gint/SDL/emscripten setup with rendering 
This basic model supports a couple of options, but mostly designed for
three targets:

* gint on fx-CG 50, with a custom XRAM-streaming rendering engine that
  is (to my knowledge) more powerful than all other existing options;

* The standard SDL/OpenGL combo for desktop platforms, using modern
  OpenGL 3.3 and some basic shaders.

* The web platform with emscripten and its OpenGL ES 2.0 API that maps
  to WebGL 1.0. OpenGL ES 2.0 code could also be used for mobile
  platforms if this ever comes up.

The current code only includes setting up the program's main loop
(update/render) as well as basic rendering.

The framework of gint's rendering engine is drawn ("shader"-based
rendering in XRAM). On the OpenGL side, some utilities are defined,
including a primitive layer of shader code compatibility for OpenGL 3.3
vs. OpenGL ES 2.0. Actual rendering is still at prototype stage.
