This is a tiny change that makes code in src/rtextures.c "fold"
correctly in editors/IDE's by matching the number of opening
parenthesis to closing parenthesis.  One of those editors is Emacs ;-)

* Fixed an issue when using raygui and physac on unix systems
hash "#" is single-line comment character in bash so echo ignores #include and #define

* tab fix

We can figure out the source file location based on the location of the
build.zig file. No need to require the library user to specify where
raylib is stored.

* make const

* make const

* follow style guide

* Update rmodels.c

* Properly fix make clean under sh.exe

* Ensure make clean works properly under Windows if RAYLIB_RELEASE_PATH is modified

This reverts commit ab47c6401e.

Tested on the following environments:
 - w64devkit.exe
 - Windows 10 cmd
 - Notepad++ NppExec console

GNU make on Windows first tries to find sh.exe on the path,
and will execute build rules using it if it is present.
The make clean target uses the builtin cmd.exe command del, which
won't work under sh.exe

The reason this is not done for the entire Makefile is because it would
break cross-compilation of raylib.

- Adds a new OS clause to build.zig for the BSDs
- Tested on my FreeBSD box using https://github.com/Not-Nik/raylib-zig
- All demos build and render just fine.  Nice !

`GetFileSize()` conflicts with the infamous `windows.h`

* Add DrawTextCodepoints

* Fixed top comment

Previously failed to build with an implicit declaration of `_NSGetExecutablePath`.

Unless these imports require to have this format, the code has been adjusted to the conventions

* Fix a signature error with the windows calls in GetApplicationDirectory for 32 bit builds.

* break is better than loop var to -1
