v0.3.0

This is the third rework of Nene (see #17), this time, less breaking than the previous rework, but some changes are hopefully for the better, this is the changelog:

• License changed from MIT to Zlib, just as SDL2.
• Now nene uses the singleton pattern, which means you can use Nene.instance() function any type to get the nene instance, instead of passing it by parameter.
• All modules uses the newer module system of nelua, just as Lua, you require the modules as local Nene = require 'nene'
• Removed core.nelua file, now, just requiring "nene" will return the main nene module only, instead of requiring all modules as before
• The SDL's wrappers are removed, now nene just calls and handle SDL directly.
• SDL libraries updated to latest ones provided by nelua-decl.
• All modules that wraps a SDL type will contain a get_raw method, which returns the wrapped value (with a nilptr check), for instance, nene uses the term "raw" to refer to any wrapped type, especially the SDL ones.
• The nene's math module is now split between various modules like nene.math.vec2, one module for each type, however, the general math module is still provided and is not considered deprecated.
• Now it's possible to use any arithmetic type for 2D vectors and rectangles using Vec2n and Rectn types, for instance, Vec2, Rect and Rectf are respectively Vec2n(number), Rectn(integer) and Rectn(number).
• As the math module, the Audio module got split between Sound and Music modules, while the Audio wraps both.
• All "destroyable" types implements the __close metamethod, including the main nene module.
• Some font metrics are added to Font module.
• Text rendering on TextTexture module it's still solid by default, but now it's possible to use blended render mode, which is much better for non-pixel-art fonts.
• Previously some functions that returned an value, ok_status now returns ok_status, value, this is done to enforce if the function run successfully.
• All the examples and documentation updated

v0.2.0

This is the version after nene-rewrite, it aims to fix the problems that I had while developing the Alpinist game.

There is still a lot of work to be done, however these changes will be pushed on main branch directly, you can either use main to get the latest updates (with chances of breaking changes) or stay stable with this release while v0.3.0 isn't released.

Enjoy!
