421 * * the tessellation evaluation shader, if active and no 422 * geometry shader is active; 423 * * the vertex shader, otherwise 424 * 425 * and clamped to the implementation-dependent point size range.

The default value 434 * is 1.0." 435 * 436 * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and 437 * OES_tessellation_point_size specifications. To summarize: if the last 438 * stage before rasterization is a GS or TES, then use gl_PointSize from 439 * the shader if written. Otherwise, use 1.0.

Because 445 * ES doesn't have a PointSize() command, the state point size will 446 * remain 1.0, satisfying the ES default value in the GS/TES case, and 447 * the VS case (1.0 works for "undefined").
