Widgets & GUI toolkits (and more)

In their shadertoys, programmers have to handle everything, and redo everything from scratch every time. For repetitive basic utilitary features like GUI or font display it can thus be very boring, so that many just don’t embed any GUI and users have to tweak defines.
Fortunately, various community members have publish useful base elements that you can reuse !
( PS: coders, please do add the tag “gui” to your utilitary shaders: for now it gathers very little ! )
