Icenowy Zheng eba15f1ba7 glamor: Fix dual blend on GLES3
The EXT_blend_func_extended extension on ESSL always requires explicit
request to allow two FS out variables because of limitations of the ESSL
language, which is mentioned as the No.6 issue of the extension's
specification.

Fix this by adding the extension request.

The original behavior on GLES3 is slightly against the specification of
GL_EXT_blend_func_extended extension, however Mesa and older version of
PowerVR closed drivers will just ignore this issue. Newest PowerVR
closed driver will bail out on this problem, so it deems a fix now.

Fixes: ee107cd491 ("glamor: support GLES3 shaders")

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
