Change order of type params to `Regl` fn and `DrawConfig`.
Change order of type params to `Regl` fn and `DrawConfig`.

In most cases, at least some of these type parameters should be explicitly supplied. I’ve tried to order them according to how likely they are to be used. `Uniforms` and `Attributes` will almost always be used, `Props` probably slightly less frequently, `OwnContext` only if one or more new context properties are being defined for the `DrawCommand`, and `ParentContext` need only be given if there are multiple nested contexts (in any other case the default context should be fine).
