* basic pbr example

pbr implementation  includes rpbr.h and few shader files header only file, which self contain everything needed for pbr rendering. Few textures and one model of the car which is under free licence which is included inside basic_pbr.c example file  currently supported shader versions are 120 and 330 , version 100 has small issue which I have to resolve

* Unloading PBRMAterial

I forgot unloading PBRMaterial

* fix small issue with texOffset assigment.

value was Vector4 at first but I found out it would be unclear for and users, so I change to have two Vector2 instead, but forgot to assign offset .

* Changed size of textures and file name changed

Changed size of textures from 2048x2048 to 1024x1024 and file name changed to shaders_basic_pbr.c ,
Added the function PBRModel PBRModelLoadFromMesh(Mesh mesh);
but GenMeshPlane(2, 2.0, 3, 3) culdn't be used because it crash once GenMeshTangents() is used with that plane mesh

* Update audio_stream_effects.c

This may slightly improve performance and be more welcoming for new users despite being an more advanced feature. 
void * usually throws an error in most compilers and it would be better to just avoid it.

Also added <stdbool.h> because booleans are, sometimes, not defined by <stddef.h>.

* Update audio_stream_effects.c

AudioInputCallBack has this
    audioFrequency += 1.0f;
    audioFrequency -= 1.0f;

cancels out each others

Added screenshot

* Added missing textures_image_kernel example in web makefile

* Added missing --preload-file for textures_image_kernel

* Added image convultion ImageKernelConvolution

* comment changes

* spelling changes and change to kernel size

* removed kernel normalization inside function

* fix to formating

* Added glsl 100 and 120 shaders to lightmap example.

* Fixed lightmap example resource loading on web.

RENAMED: `DrawLine<spline_type>()` to `DrawSpline<spline_type>()` for more consistent and clear naming
REVIEWED: Bezier drawing parameters order, more consistent
REVIEWED: Spline-based examples -WIP-

Example is intended for `PLATFORM_DESKTOP` only and OpenGL 3.3 Core profile.

* add example for deferred rendering/shading

* adapt convention
