A GLenum specifying which WebGL capability to enable. Possible values:
gl.BLEND Activates blending of the computed fragment color values. See WebGLRenderingContext.blendFunc().
gl.CULL_FACE Activates culling of polygons. See WebGLRenderingContext.cullFace().
gl.DEPTH_TEST Activates depth comparisons and updates to the depth buffer. See WebGLRenderingContext.depthFunc().
gl.DITHER Activates dithering of color components before they get written to the color buffer.
gl.POLYGON_OFFSET_FILL Activates adding an offset to depth values of polygon's fragments. See WebGLRenderingContext.polygonOffset().
gl.SAMPLE_ALPHA_TO_COVERAGE Activates the computation of a temporary coverage value determined by the alpha value.
gl.SAMPLE_COVERAGE Activates ANDing the fragment's coverage with the temporary coverage value. See WebGLRenderingContext.sampleCoverage().
gl.SCISSOR_TEST Activates the scissor test that discards fragments that are outside of the scissor rectangle. See WebGLRenderingContext.scissor().
gl.STENCIL_TEST Activates stencil testing and updates to the stencil buffer. See WebGLRenderingContext.stencilFunc().
When using a WebGL 2 context, the following values are available additionally:
gl.RASTERIZER_DISCARD Primitives are discarded immediately before the rasterization stage, but after the optional transform feedback stage. gl.clear() commands are ignored.
