A3DGE Code

* Fixed Ta3dMatrix3D constructors: Some where "transposed" resulting in
incorrect coordinate transformations.
* Fixed gnomon orientation.
-+ ex_test_linear renamed as ex_rc_car.
+ Added a few documentation to ex_rc_car.

* Fixed Ta3dEventManager.DispatchEvents: events queued and wasn't dispatched
properly due to bad loop ending (Exit instead of Break).

+ Added unit a3dge.Model3d and started the Ta3dModel3D class.

+ Added fog to scene.
+ Added default materials.
+ Added a few more code to ex_test to help testing things.

* Property Ta3dModelObject3d.LODMesh renamed to LODModel.
+ Added Ta3dMatererial.
+ Added color constants.
* Fixed Ta3dModelObject3d.Render.
* Documentation updates and fixes.

* Fixed matrix building functions: OpenGL use degrees but Pascal uses radians.
* Camera "ApplyMatrix" methods doesn't load identity.
* Ta3dCamera.ApplyMatrix is virtual now.
* Fixed ex_test_linear program.
* Trying to fix ex_test but camera doesn't works as expected (there's something
weird, maybe I forgot something).
* Documentation update.

* Fixed makefile.
- Removed a lot of inline as they seem not been used. They should back though.
* Fixed gnomon.
+ Added a test program to test linear, vectorial maths.
* Documentation updates.

(Note ex_test doesn't work on Windows 11 at least!)

- removed "Initializing component" log message from component manager.
* Fixed "OnMove" event of mouse componente.
