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

It's quite optimized now.

azrp: bump command limit to 1024 
It used to be 256 due to XYRAM limits but it's easy to hit.

libnum: add experimental string representation 
Currently only has hand-picked tests and very rough code, but it's a
start. In the future, I want to have better tests, more
options like printf's %e/%f/%g, and more versatile methods.

libnum: rename the namespace [num] -> [libnum] 
The first name would make `num` on its own ambiguous when using the
namespace.

libnum: add performance tests for num32 2022-07-24 00:21:56 +01:00
Lephenixnoir 708ba1b017
libnum: unit tests, perf tests for num16, double limits 
* Add a unit testing framework in libnum/test/. Assertions are checked
  against sparse sets of input values (a couple thousands for each
  type), distributed fractally.
* Add performance tests for num16.
* Fix an overly ambitious substitution of /256 by >>8 in num16::mul,
  which would give some incorrect results for negative results.
* Also fix an incorrect sign extension in the num16->num32 conversion.
* Express comparison-with-int operators in terms of the integer even
  though some versions are faster when expressed in terms of the fixed-
  point value. This is because the integer is frequently known at
  compile-time.
* Add minDouble and maxDouble static members to each num type to
  programmatically supply the bounds of the type.

libnum: add tests for how optimized compiled assembly code is 
This change adds tests for libnum (run with `make -C build-x tests`)
that compile example programs with g++ and evaluate how optimized the
assembly code is. This is done by checking user-provided specifications
of what instructions should and shouldn't be used against the compiled
assembler.

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.

meta: move submodules to 3rdparty/ (still internal) 
This properly separates the libraries developed here from the (now
clearly) third-part software that we build at the same time.

There is still no install script for these libraries, they are only
usable from the main CMakeLists.txt. This will change soon.

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.
