* render: Introduce render context object.David Thompson2019-10-111-60/+43
| | | | | | | | | | Due to the declarative modules feature of Guile 2.9.4+, the existing technique of using one top-level variable per GL state was very broken because the initial values got cached at all call sites and state updates were being silently ignored and thus the game window was always a black screen. Not good! By replacing all of the state variables with a single "context" object and poking at fields inside, things work again and it's arguably the better design anyhow.
