As the submitter said "in general it is preferred due to better
performance", why don't we just have, in webkitgtk:

    select BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_GL if BR2_PACKAGE_GST1_PLUGINS_BAD

Or even further:

    select BR2_PACKAGE_GST1_PLUGINS_BAD
    select BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_GL

Of course, that requires propagating the required dependencies...
But since webkitgtk already depends on libgtk3, which itself depends on
LIBEGL_WAYLAND or LIBGL, we're not too far off...

Sorry, I am still not convinced that using 'imply' in Buildroot is a
good idea overall... :-(

On the other hand, this is webkitgtk we're speaking here. It's already
huge, really huge. What would be the problem with 'select'ing
GST1_PLUGINS_BAD_PLUGIN_GL if it is known to be the 'best' solution
(even if not strictly required) ?

But I'm done speaking about it now.
