Module call 

Built-in functions call implementations.

Functions bear the same name as the WGSL counterpart. Functions that take template parameters are suffixed with _t and take tplt_* arguments.

Warning

Some functions are still TODO and are documented as such. Derivatives and texture functions are also missing.

Usage quirks

• The arguments must be loaded.
• User-defined functions can shadow WGSL built-in functions.
• Type aliases must be resolved: WGSL allows calling functions with the name of the alias.
