-Added some more math functions
-fixed many memory leaks
-added AABB and BVHTree support to collision.d
*BVHTree has only incrementally adding entities implemented by now (and bad BottomUp algorithm)
*ECS Systems use two trees, one for static and one for dynamic entities, dynamic BVH is builded every frame from scratch by now
-BrickBreaker now uses BVHTree to collision detection
*balls only use tree for checks (they aren't adding to tree)
-fixed bug leading to crash
-fixed code do cross compiling to android
-fixed build with GCC (workaround)
-added little benchmark
-several small fixes
-updated meson build (demos building, working with GCC, LDC and DMD)
-added some meson options
-added ImGUI bind for OpenGL3
-added webpage deploymnet stage
-added separate build stage which build all binaries and generate documentation
-added Emscripten build stage for merge to master only
-added VBO batch rendering (current default, no render mode switch yet)
-fixed camera positioning calculation
-fixed buffer issue with WebGL
-added viewport scalling (at least 300 pixels height). Pixels are scalled if screen is bigger.
-center demos gameplay area
-added fullpage html template for Emscripten build
*updated build scripts
*removed tls variables from code (needed to support WebAssembly)
*some mmutils tweaks
*some fixes
*pthread TLS thread ID implementation
-added Atomic file (reimplementation of atomics templates for emscripten)
-added emscripten support to ecs.std
