@luma.gl/webgl clear func causing an error

[sakitam-fdd]

The status related to stencil seems to be set to the depth state, and I am not sure if this is intentional or a bug

It looks like you are debugging your app with spector js and spector tries to read some data from luma.gl and does not see what it expected?

Not sure how to help you debug this.

@ibgreen
It occurs when clear is called, as shown in the following code

import { Framebuffer, Renderbuffer, Texture2D, clear } from '@luma.gl/webgl';

// other render pass
clear(this.gl, {
  color: true,
  stencil: true,
  // depth: false,
});

The error was raised when the depth parameter was not specified, and I noticed that when stencil was specified without depth, clearStencil had a value of null

if (stencil) {
  clearFlags |= GL_STENCIL_BUFFER_BIT;
  if (depth !== true) {
    parameters.clearStencil = depth;
  }
}

OK understood, yes it looks like a bug.
