/* In OpenGL ES, it is legal to omit the point size write from the geometry
* shader when drawing points. In this case, the point size is
* implicitly 1.0. We implement this by inserting this synthetic
* `gl_PointSize = 1.0` write into the GS copy shader, if the GS does not
* export a point size while drawing points.

* This should not be load bearing for other APIs, but should be harmless.
