There are multiple #define values around raylib, usually not exposed for redefinition, just reviewed all of them to allow users redefining them on compile time if required.

Also, multiple #define have been renamed and commented.

Actually this function is useless and potentially dangerous, internally, a shallow copy of data was done. Same could be accomplished accesing image.data directly.

To unify with DrawText*() equivalent functions

* [cppcheck] Improvements in SaveStorageValue() in core.c

in file core.c cppcheck shows errors only in function SaveStorageValue():

* Common realloc mistake: 'fileData' nulled but not freed upon failure
* Memory pointed to by 'fileData' is freed twice.

Validation:
* Tested examples/core/core_storage_values.c
* Launched Unit Test for this function
* Rerun CPPCHECK afer fix

* [cppcheck] Change functions header to accept only positive position in files

Changes:
* Functions SaveStorageValue(), LoadStorageValue() (core.c)
* Functions LoadFileData(), SaveFileData() (utils.c)
* Headers in raylib.h

Validation:
* Tested examples/core/core_storage_values.c
* Launched Unit Test for these functions
* Rerun CPPCHECK afer fix

* Update ImageDraw*() functions to match arguments of Draw*()

Updated draw functions:
ImageDrawPixel()
ImageDrawPixelV()
ImageDrawCircle()
ImageDrawCircleV()
ImageDrawLine()
ImageDrawLineV()
ImageDrawRectangle()
ImageDrawRectangleV()
ImageDrawRectangleRec()

* [nodepadpp] Update Notepad++ ImageDraw defintions

This updates the Notepad++ definitions with the updated ImageDraw methods.

* [examples] Add ImageDraw calls to textures_image_drawing

* Update ImageDraw*() methods

Added draw functions:
ImageClearBackground()
ImageDrawPixel()
ImageDrawLineEx()
ImageDrawCircle()

Improved file access checks

Renamed functions for consistency:

 - StorageLoadValue() > LoadStorageValue()
 - StorageSaveValue() > SaveStorageValue()

There could be some cases where we need to define the internal audio buffer size, now it's possible.

RENAMED: InitAudioBuffer() to LoadAudioBuffer()
RENAMED: CloseAudioBuffer() to UnloadAudioBuffer()

Renamed some defines and reviewed some comments.

* [core] REDESIGNED: Implement global context

* [rlgl] REDESIGNED: Implement global context

* Reviewed globals for Android

* Review Android globals usage

* Update Android globals

* Bump raylib version to 3.0 !!!

* [raudio] REDESIGNED: Implement global context

* [raudio] Reorder functions

* [core] Tweaks on descriptions

* Issues with SUPPORT_MOUSE_GESTURES

* [camera] Use global context

* REDESIGN: Move shapes drawing texture/rec to RLGL context

* Review some issues on standalone mode

* Update to use global context

* [GAME] Upload RE-PAIR game from GGJ2020 -WIP-

* Update game: RE-PAIR

* [utils] TRACELOG macros proposal

* Update config.h

REMOVED: IsTouchDetected()

Addressing issue #1056

- Renamed GetGlyphIndex() parameter
 - Review DrawTextEx() implementation
 - Review DrawTextRecEx() implementation

* swapped comments, expanded comment for clarity

* revert alignments

* adjusted for consistency

Keeping original API

* add api FIFO based character input.

* rename input character functions

* replace tab to space x4 #1012

ADDED: CodepointToUtf8()

RENAMED: TextCountCodepoints() -> GetCodepointsCount()

* Initial commit of addition for GLTF materials.. should support loading more than just albedo map.

* Clean up

* fixed seg faults and leaks

* temp don't overwrite defuse colour when rendering

* undid something dumb!

* correctly mixed diffuse map color when rendering to preserve not overwrite it

Get the unicode equivalent characters (as int array) from a UTF-8 text array... maybe this function is renamed to be clearer to users...

* Const corectness for LoadShaderCode

* Added const for standalone variant as well.

- ADDED: CompressData()
 - ADDED: DecompressData()

...moved to internal AudioBuffer structure as totalFramesProcessed, now time measure works again... but there is some problem with looping...
Also note some inconsistencies between frames and samples, it seems those concepts are not considered correctly in the code.

raylib logo animation has been removed. That funtionality was very restrictive, not configurable at all and hardly ever used, also, it added a coupling dependency of `core` module with `shapes` and `text` modules.
