Game Sprites in Dogelog Notebooks (Re: ANN: Dogelog Player 1.3.2 (XML Interpolation))

Dogelog Player is a Prolog system mostly written in
Prolog itself. It is available for the JavaScript,
Python and Java platform. It offers a minimalistic
subset of the ISO core standard for Prolog, dubbed
by the name Novacore.

It further features a minimalistic library to access
the Browser environment. The content of the library is
developed with hindsight of its usage in Dogelog
Notebooks. Here we give a glimps of its usage
for Game Sprites.

With a little programming discipline the library(vector)
makes it possibly to design games for different screen
resolutions. To ease the Dogelog Notebook orchestration
of the animation of multiple game sprites via cooperative
multitasking from create_task/1, we introduced
group_gather_async() and group_teardown().
