Manual Content: Several shader functions should be documented because they are not able to be shown in autocomplete inside the IDE

[gm-bug-reporter]

Description

While the functions "float CalcFogFactor(vec4 pos)", "vec4 DoDirLight(vec3 ws_normal, vec4 dir, vec4 diffusecol)", "vec4 DoPointLight(vec3 ws_pos, vec3 ws_normal, vec4 posrange, vec4 diffusecol)" and "vec4 DoLighting(vec4 vertexcolour, vec4 objectspacepos, vec3 objectspacenormal)" are defined and accessible in vertex shaders, this is not documented or supported by the IDE (not syntax highlighted). This should at least be documented as writing a function with one of these names and parameters would lead to an unexplained compilation error. The same goes for the functions "void DoAlphaTest(vec4 SrcColour)" and "void DoFog(inout vec4 SrcColour, float fogval)" in fragment shaders.

Which version of GameMaker are you reporting this issue for?

IDE v2024.8.1.171 Runtime v2024.8.1.218

Which operating system(s) are you seeing the problem on?

Windows 10.0.22631.0

We cannot currently do the autocomplete in the editor, but we can add them to the manual.

Listed the functions on the Shaders page. Also added a bit of structure to the page, dividing the text in sections.
