For the Metal shader translation support for shader-global uniforms are remapped via macro's, and in such cases where a uniform name matches a vertex attribute name, compilation errors will occur due to this injected syntax being incompatible with the immediate code.
Also adding source-level function interface alternatives where sized arrays are passed in. These are not supported directly in Metal shading language and are instead handled as pointers. These pointers require explicit address-space qualifiers in some cases, if device/constant address space memory is passed into the function.

These implementations remove dependency on the Geometry pass by instead invoking one vertex shader instance for each expected output vertex, matching what a geometry shader would emit. Each vertex shader instance is then responsible for calculating the same output position based on its vertex_id as the logic would in the geometry shader version.
SSBO Vertex fetch enables full random-access into a vertex buffer by binding it as a read-only SSBO. This enables each instance to read neighbouring vertex data to perform contextual calculations as a geometry shader would, for cases where attribute Multiload is not supported.

Sun Disc is currently not supported because it'll need special handling - on the one hand, I'm not sure if Eevee would handle a 1e6 coming out of a background shader without issues, and on the other hand it won't actually cast sharp shadows anyways.
I guess we'd want to internally add a sun to the lamps if Sun Disc is enabled, but getting that right is tricky since the user could e.g. swap RGB channels in the node tree and the lamp wouldn't match that.
Anyways, that can be handled later, the sky itself is already a start.

Shader and compositor curve nodes change their inputs even if they are
at identity settings.
That is because shader and compositor curve nodes evaluate their curve
map texture samplers at the normalized input directly, disregarding the
fact that the samplers are evaluated using linear interpolation. This
causes the output to be slightly different that it should be.
This patch remaps the evaluation parameters such that the texture
sampler is evaluated at the center of the pixels.

This replaces the direct shader uniform layout declaration by a linear
search through a global buffer.
Each instance has an attribute offset inside the global buffer and an
attribute count.
This removes any padding and tighly pack all uniform attributes inside
a single buffer.
This would also remove the limit of 8 attribute but it is kept because of
compatibility with the old system that is still used by the old draw
manager.
This was an oversight as the matrix multiplication present in original
code was reversed.

This was caused by un-wanted normalization. This is a requirement of
the MikkTspace. The issue is that g_data.N is expected to be normalized
by many other functions and overriden by bump displacement.
Adding a new global variable containing the interpolated normal fixes the
issue AND make it match cycles behavior better (mix between bump and
interpolated normal).
Workaround the issue by adding an intermediate function. This is usually
the case when working with attributes.

The realtime compositor sometimes produces fuzzy results when the
interpolation is set to bilinear. This was due to the domain realization
shader, which incorrectly sampled the input image.
This patch fixes such fuzziness by introducing a 0.5 offset to evaluate
the sampler at the center of pixels. Additionally, it makes sure the
centring offset is an integer offset by taking its floor, retaining the
previous 0.5 offset even with the difference in size is odd.
