[FIXME: source]                                    11/18/2024                                 GLDELETESHADER(3G)

glDeleteShader frees the memory and invalidates the name associated with the shader object specified by
       shader. This command effectively undoes the effects of a call to glCreateShader().

       If a shader object to be deleted is attached to a program object, it will be flagged for deletion, but it
       will not be deleted until it is no longer attached to any program object, for any rendering context
       (i.e., it must be detached from wherever it was attached before it will be deleted). A value of 0 for
       shader will be silently ignored.

       To determine whether an object has been flagged for deletion, call glGetShader() with arguments shader
       and GL_DELETE_STATUS.

GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.
