[OpenLayers-Users] setOpacity does not work on google layers

[joaorodr84]

After further investigation, I was able to better understand how the Google
layer works.

The Google layer is inside a Google maps container. The OpenLayers map is
also put inside the DIV of the Google map. The DIV of the google map has the
following CSS:

*
    /* GMaps should not set styles on its container */
    .olForeignContainer {
        opacity: 1 !important;
    }
*

The opacity of the google layer can't be changed, because of the
"!important" property. I tried to modify the default OpenLayers style, by
removing the "!important" property, but setting the opacity in the Google
layer, sets the opacity of the whole DIV containing the Google map, and
subsequently sets the opacity of the entire OpenLayers Map (considering that
it is contained in the DIV of the Google map).

For now, I can't find a fix for this issue. 

Could someone please help me with this issue? I want to know if it is even
possible to set the opacity of a Google layer in the current version (2.13).
Thanks
