add touch support

comma backend

* Improve cmake config file generation

This allows for finding raylib on a non-standard location (eg, not in /usr/lib{,64})

* Only have glfw as private if using internal glfw and not static

Is now possible to switch platform

Is now possible to diable raudio, rmodels, and so on

Made getOptions public so it can be used for zig wrappers

* 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 to 5.5 version  of eexample and fix to work in web

set GLSL_VERSION            100

set precision highp float;
removed in keyword
fix for loop has to use only constant

* Update shader_basic_pbr example to work on web

changed to GLSL_VERSION            100
update glsl100 shader
set float  precision  to highp
removed keyword  in
change for loop tu use constant value  gives an error

* Update shader_basic_pbr example to work on web

changed to GLSL_VERSION            100
update glsl100 shader
set float  precision  to highp
removed keyword  in
change for loop tu use constant value  gives an error

* removed rpbr.h

removed rpbr.h

* increased vertex data precision to match blender exports

* modified memory allocation to better fit higher precision data

* now accounting for newline characters during allocation

* now accounting for potentially higher vertex counts

* removed unnecessary final newline

According to https://github.com/electronstudio/raylib-python-cffi

Changed line 118 from, "// For advance camera controls, it's reecommended to compute camera movement manually", to, "// For advanced camera controls, it's recommended to compute camera movement manually".

[raylib-cpp](https://github.com/RobLoach/raylib-cpp) has been updated to use the new raylib 5.5 functions. This is a great release! Thanks so much.
