a stripped down version of stb_truetype.h

WHY AND WHAT?

Since I only use the "old" 3D API in my project, I removed all unrelated stuff and tried to "upgrade" the original code to C++.

This lib is perfect if you just need following functions to generate a simple atlas-bitmap for further use with e.g. OpenGL:

• stbtt_InitFont()
• stbtt_GetCodepointBitmapBox()
• stbtt_BakeFontBitmap()
• stbtt_GetBakedQuad()

CONVERSION TO C++

WHAT I DID SO FAR:

• fixed all warnings reported by PVS-Studio and clang-tidy (use brackets etc.)
• replaced "malloc/free" with "new/delete"
• replaced all C-style casts with modern-style C++ cast (e.g. static_cast)
• initialised all variables and narrowed their scopes if possible
• fixed all implicit float-to-double-conversions by consequent use of the float literal (e.g. 0.0F)
• made everything "const", what can and should be const
• replaced C headers with the corresponding C++ headers
• used STL functions like "std::max" or "std::swap" where possible, replacing the old implementations
• replaced C-style arrays with std::vector (but, of course, this is still in work)
• tagged all functions as "inline"
• replaced "NULL" with "nullptr"
• removed all implicit casts by being more expressive/use of castings
• used "enum class" instead of plain enums
• replaced "int" / "unsigned int" with fixed width integer type "std::int_fast32_t"
• replaced "unsigned short" with fixed width integer type "std::int_fast32_t"

FURTHER NOTES:

• removed Rasterizer version 1
• removed new 3D API
• removed all assert()
• no support for stb_rect_pack.h
• no implementation with other RAD tools
• removed font name matching API
• removed most of the "the macro-preprocessor-magic"

TO DO:

• get rid of all these raw pointers
• work on replacing arrays with std::vector
