04a986db73 Add new Renderers page 
Adds a new page which gives a summary of the three renderers. This page briefly
describes the renderers, gives some guidance on how to choose a renderer. It also
contains a comparison table between the renderers.
Adds an entry in the FAQ which links to this new page.
Adds a note about subsurface scattering limitations to the Standard Material page.
Adjusts some other pages which had incorrect information.

b757d4019d Add warning about uninitialized variables in shaders 
Adds a warning note to shading_language.rst. GDShader does not
initialize local variables to 0, and an uninitialized local variable can
contain an arbitrary value.

67e37b547c Add notes on bit depth for ints and floats (#10028) 
* Added notes on bit depth for ints and floats

Added a small note about the bit depth of integers and floats in Godot's shading language as it is not explicitly stated anywhere.

The bit depth of integer and floats in GDscript and Godot's shading language are different, which can cause problems with lost precision in calculations when integers are set from GDscript as floats/ints in GDscript are 64 bits instead of 32 bits (the standard in GLSL ES 3.0).

While most are unlikely to run into problems due to this difference in bit depth, it can cause mathematical errors in edge cases. As stated by previous contributors, no error will be thrown if types do not match while setting a shader uniform. This includes GDscript floats being set as Godot shader floats (which may not be intuitive).

Added/changed description of TIME in CanvasItem, Fog, Particle, Sky, and Spatial shader pages. Description now links to other relevant docs pages. Added a label to the global uniform header of shading_languge.rst, so it can be cross referenced from elsewhere.

99da9754d1 Entering transparent pipeline when reading ALPHA 
It's just a minor change, but I got confused on why the material was still using the transparent pipeline even though I removed all writes to ALPHA. So adding this should clarify things.
