Explicit constructor for mat3 from a mat4 is not valid and cannot be overloaded.
Adding explicit texture resource type flags for depth textures. This is an explicit requirement for Metal Shading language. This is a temporary compatibility, as this path is already supported in GPU_SHADER_CREATE_INFO under ImageType::DEPTH_2D, though required in shader source for MSL shaders which do not have create info.

Metal shading language follows the C++ 14 standard and in some cases requires a greater level of explicitness than GLSL. There are also some small language differences:
- Explicit type-casts (C++ requirements)
- Explicit constant values (C++ requirements, e.g. floating point values using 0.0 instead of 0).
- Metal/OpenGL compatibility paths
- GLSL Function prototypes
- Explicit accessors for vector types when sampling textures.
