…closely * converted non-void pointers to '[*c]' (C pointers) * converted void pointers to '?*anyopaque' * converted non-GL types to GL types * added 'const' where needed * adjusted argument names to match those in the registry
* makes it possible to unset the debug callback, by passing in 'null'

Pull Request Overview
This PR standardizes pointer type declarations in OpenGL bindings for Zig, converting from inconsistent pointer types to the more appropriate [*c] (C pointer) convention and nullable optionals where appropriate.
Key changes include:
- Converting single-item pointers (
*const Type) to C pointers ([*c]const Type) for consistency with C FFI - Converting bare pointer types to nullable optionals (
?*const anyopaque) where nullability is semantically valid - Renaming parameters to match OpenGL specification conventions (e.g.,
binary_formattobinaryFormat,shader_typetoshadertype) - Removing unnecessary
@"type"escaping in parameter names

`bindings.zig` changes: * used literals instead of variables for enums in OpenGL 4.2, * moved `DEBUGPROC` to the beginning of OpenGL 4.3, * adjusted wrong enum name from `VIEW_CLASS_RGTC1_RG` to `VIEW_CLASS_RGTC2_RG` in OpenGL 4.3, * added missing enums to OpenGL 4.4, * removed enum `TEXTURE_BINDING` from OpenGL 4.5, * changed ARB enums to non-ARB ones in OpenGL 4.5, * added missing enums to OpenGL 4.5, * added `POLYGON_OFFSET_CLAMP` to OpenGL 4.6, * added spacing between sections. `wrapper.zig` changes: * added changes from merge zig-gamedev#25 to wrapper placeholders, * applied enum changes done in `bindings.zig`, * moved `DEBUGPROC` to the beginning of OpenGL 4.3, * added many missing enums to OpenGL 4.3, * added missing function placeholders to OpenGL 4.3, * added missing function placeholders to OpenGL 4.5, * return type of `getGraphicsResetStatus` uses non-ARB enums in OpenGL 4.5, * added spacing between sections.
