Basic packing algorithm currently follows this order: Copy pixel data -> Move offsetX for current glyph -> Check remaining space for current glyph...
Since X offset already moved according current glyph, remaining space should be checked for next glyph. Because of this, occasionally, current logic causes glyphs wrapping around texture.
Proposed fix accomplishes that by moving offsetX check to the beginning of the loop.

* Calculate exact image size in GenImageFontAtlas

Calculate exact image size with a method based on total glyph width and glyph row count
Current method seemed a little bit overkill with square root, log and power functions and only approximates image size which can be wonky with some weird fonts like cursive fonts.
Proposed method calculates image size directly with a simpler method and results exact image size needed.

* Update rtext.c

* Update rtext.c

Changed do-while to while loop, and also added an extra step to calculate maximum glyph width and excluding it from image width for extra safety.

Upate -> Update

* Add const qualifier to char * path argument
in qoa_open()

* Remove unnecessary cast

The `qoaplay_open()` function expects a `char *`, but we are passing in a `const char *`. While this works just fine, it does issue a compiler warning when strict:

```
src/raudio.c: In function ‘LoadMusicStream’:
src/raudio.c:1290:45: warning: passing argument 1 of ‘qoaplay_open’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
 1290 |         qoaplay_desc *ctxQoa = qoaplay_open(fileName);
      |                                             ^~~~~~~~
In file included from src/raudio.c:233:
src/external/qoaplay.c:86:34: note: expected ‘char *’ but argument is of type ‘const char *’

      |                            ~~~~~~^~~~
```

This change casts the argument to a `char *` to fix the warning.

REVIEWED: rcamera module formating
REVIEWED: `core_3d_camera_example`

It was quite restrictive and hacky implementation, just load multiple types same sound to play multiple instances.

Changes the DLL export condition to apply to platform WIN32 instead of
compiler MSVC

Some format tweaks

It shouldn't matter much but it could avoid some conflicts with other libraries in the future (like `tinyfiledialogs`).
