    `environ` needs to be declared for (at least) FreeBSD.
    
    Declaring it unconditionally seems to build fine on all other platforms.

    GL_ANGLE_multiview has been renamed to GL_OVR_multiview2.
    
    changes include:
    1) GL_OVR_multiview to GL_OVR_multiview2 extension directive change
    2) Removal of all references to side by side. We no longer support multiple views in a single 2DTexture. Only 2DTextureArray's are supported
    3) WebGL 2 (ES3) is required for multiview

    Don't clamp in glBlendColor if context supports renderable [half-]float.
    
    Add test for glBlendColor >1.0, skipped on D3D9 since it's unsupportable
    there.

    Add support to CHROMIUM_color_buffer_rgba for creating RGBA32F renderbuffers on ES2.
    
    This is desired for implementing WEBGL_color_buffer_float support on
    WebGL1 on ANGLE's ES2 driver, for Firefox.

    Update texure cache after teleting bound texture.
    
    The texture cache could become out of sync. And we could end up
    dereferencing an invalid pointer.
