Finally, fixed bugs in bigint implementation as well as switched to
32/64 bit integer implementation (gained 2x speed up in some cases).
Additionally, I decided to split Float.c into Float.c and BInt.h for
better readability.
Finally added StringToDouble function (should work for the majority of
the cases). Additionally fixed bug in StringFromDouble related to
incorrect rounding and added asserts (should add more asserts in the
following commits).
Also implemented some optimizations from Burger and Dybvig paper.
Added initial implementation (or wrapper) of the threading library.
It's rather basic, but should work for most of the tasks.
Unfortunately, spinlock implementation relies on GCC/Clang compiler
built-ins (or in-worst-case-scenario on Win32 - InterlockExchange).
In the future, I should revisit this code and fix/reimplement some stuff
(or add support for Windows XP).
Added some basic geometric primitives such as planes, rays, segments
and lines (plus some extra functions like xProject, xBarycentric, Lerpf),
as well as some intersection tests between them.
Additionally, I split massive math test into smaller ones and tweaked
unit test library (testing no longer stops after first failure).
After a while I felt that putting underscores between words was not the
best solution, so I changed the underscores to capital letters.
Fixed consistency bug between POSIX/Win32 platform in BH_FileOpen.
Removed definitions for math types (vector, matrix, etc.) due to
potential aliasing issues.
Linking against static asan library was a mistake. Now this should
work better for other compilers. Also added script for running all tests
under different profiles.
Added Asan profile to help catch and fix various bugs (and indeed, there
were few of them).
Additionally, fixed bhunit macro to process arguments only once.
After some testing, I decided to ditch the DirectX approach of writing
math functions.
Additionally, I added unit tests (with reference wxMaxima calculations)
for most math functions and fixed several bugs along the way.
