Support creating a 3x3 pixels white rectangle at the bottom-right corner of the generated font atlas image, useful for shapes+text drawing in a single draw call!

This reverts commit 70286c7cdc.

Working from wsl and compiling for windows this change makes it much easier to compile a static library for windows on arm.
To compile a static library for windows on arm:

```
make PLATFORM=PLATFORM_DESKTOP TARGET_OS=WINDOWS CROSS_CC=/llvm/bin/aarch64-w64-mingw32-gcc CROSS_AR=/llvm/bin/aarch64-w64-mingw32-ar
```

This does not work to compile a shared library yet, only static.

* [example] Core Input Gestures for Web

* Fix Doubletap for web

* Changes TAP_TIMEOUT and rgGetCurrentTime to seconds

This reverts commit e190b7eee9.

Change C3 to Zlib
Update Raylib-nelua's name as Raylib.nelua to reflect repo change.
Update Raylib.nelua licence to Zlib

Just updated

* Add options to zig compile options

Support for compiling with raygui, raymath, and physac.
Also outputs the required headers.

Raygui should be located `../raygui` relative to the repo root
Physac should be located `../physac` relative to the repo root

This behavior matches options in the Makefile

* Move Options struct

* Remove physac, explicit raymath, always copy rlgl.h and raymath.h

* Remove unused options from build.zig

* Add srcdir as include path for raygui.h
