The vertex shader always gl_PerVertex, but the tesselation shaders only
define the structure when the point size extension is enabled, otherwise
gl_PointSize is passed as a generic varying and can not be written to.
If one enables the extension based on whether the value gl_PointSize is
actually accessed in the tess shaders then it might happend that tess_ctrl
doesn't touch the value, and the extension isn't enabled, and tess_eval
accesses it and the extension is enabled. In such a case gl_PointSize is
passed as a generic to and from the tess_ctrl shader and linking of the
shaders will fail because of different definitions of gl_PerVertex.
Since in this case there is no indication in the tess_ctrl shader that
point_size is accessed, and it is not known whether the shader will be
linked with a tess_eval shader that uses gl_PointSize the workaround is to
always enable the extension for all tesselation shaders.

When using OpenGL ES 3.1, we either need to emit a precision qualifier,
or set a default precision.
Since it's not unthinkable that we'd want to forward lowp/mediump

to get this right later on.
