3.20.1

This is a small patch release that fixes a few bugs in the library. As a little bonus, a tiny portion of the Core module was moved to a new Core/Base subfolder. If you would like to use BBMOD only for rendering of 3D animated models in your GameMaker project, without using its material system and other capabilities, this is the only folder that you need to import into your project.

Changelog:

• Renderer BBMOD_DeferredRenderer now also supports the DepthOnly render pass and blends depth of forward rendered models into the G-Buffer.
• Fixed normal mapping on terrain.
• Fixed spot lights affecting backsides of models.
• Fixed materials BBMOD_MATERIAL_DEFERRED and BBMOD_TERRAIN_DEFERRED being registered under wrong names and hence being loaded incorrectly from BBMAT files.
• Fixed crash that happens in recent releases of GameMaker in function bbmod_texture_set_stage_vs when running on macOS and libBBMOD.dylib is missing.
• Fixed method RotateOther of BBMOD_Quaternion.
• Fixed method ScaleSelf of BBMOD_DualQuaternion.
• Property Materials of BBMOD_Model can now contain also Pointer.Textures instead of BBMOD_Materials, but then the model can be rendered only using the submit method!
• There is now a new folder BBMOD/Core/Base, which contains the absolute minimum required to use BBMOD's animation player in your GameMaker projects. The material system is not included in this folder, meaning you will need to write your own shaders to draw the models. Do not forget to add #macro BBMOD_MATERIAL_DEFAULT -1 to your project if you import only this folder!
