7303e5733e Clarify use of source_color in Shading Language 
Rewrite section on using the source_color uniform hint. Content is mostly the same,
but is more clear.
Rename one instance of "shader hint" to "uniform hint".
Adds a section header for Uniform hints.

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).

badeecb28a Add info to turn off preview sunlight before working with 3D shader lighting. 
By default in Godot 4.3, preview sunlight is enabled and only disabled by a DirectionalLight3D being added to the scene. If you follow the guide and add an OmniLight3D, the preview sunlight stays enabled and causes a drastically different look.

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.
