* Fix formating problems with GetApplicationDir.
Don't ever return an empty string

* always return a valid path even if it's ./

* remove the need for the dll and just use the normal GetModuleFileName function

* Add a function to return the application directory.

* CI fixes

The previous implementation somewhat break the expected behaviour for games and examples when pressing the `Fullscreen` button in the provided `shell.html`.

Just reverted for the moment for further investigation.

* Added drawing text with shadow

* Added SetWindowOpacity()

* Edited Mis-spell

* Fixed conventions

Allow to choose which modules are compiled with raylib, if some modules are excluded from compilation, required functionality is not available but smaller builds are possible.

* Expose GetRenderWidth and GetRenderHeight functions

* Fix scissor on macos

* Fix typo

MAX_DIRECTORY_FILES macro removed.
ClearDirectoryFiles() tweaked to reflect changes.

- All variables are initialized on declaration, some arrays were not properly initialized
 - Static array buffers require memset() for re-initialization on every function call

Register keys independently of the actions

This function is not required, users can check it with `GetGamepadName()`

* - support create OpenGL debug context in OpenGL 4.3

* - additional events in debug message
- fixed glEnable(GL_DEBUG_OUTPUT)

* Reviewed OpenGL Debug Context

Those defines are only used inside `rlgl` module

* [rcore] fix rpi4 Failed to get DRM resources

card1 is not always the the correct card to use on rpi4
rpi os finds the correct card and links it to /dev/dri/by-path/platform-gpu-card during boot.
this fix makes sure that we always point to the correct card on rpi4

* Update rcore.c

raylib modules have been slightly renamed to add some identity and note that they are independent modules that can be used as standalone separate parts of raylib if required.

The renamed modules are:
 - `core` -> `rcore`
 - `shapes` -> `rshapes`
 - `textures` -> `rtextures`
 - `text` -> `rtext`
 - `models` -> `rmodels`
 - `camera` -> `rcamera`
 - `gestures` -> `rgestures`
 - `core` -> `rcore`

All the build systems has been adapted to this change.
