284 * written by:
285 *
286 * * the geometry shader, if active;
287 * * the tessellation evaluation shader, if active and no
288 * geometry shader is active;
289 * * the vertex shader, otherwise
290 *
291 * and clamped to the implementation-dependent point size range. If
292 * the value written to gl_PointSize is less than or equal to zero,
293 * or if no value was written to gl_PointSize, results are undefined.
294 * If program point size mode is disabled, the derived point size is
295 * specified with the command
296 *
297 * void PointSize(float size);
298 *
299 * size specifies the requested size of a point. The default value
300 * is 1.0."
301 *
302 * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
303 * OES_tessellation_point_size specifications. To summarize: if the last
304 * stage before rasterization is a GS or TES, then use gl_PointSize from
305 * the shader if written. Otherwise, use 1.0. If the last stage is a
306 * vertex shader, use gl_PointSize, or it is undefined.
307 *
308 * We can combine these rules into a single condition for both APIs.
309 * Using the state point size when the last shader stage doesn't write
310 * gl_PointSize satisfies GL's requirements, as it's undefined. Because
311 * ES doesn't have a PointSize() command, the state point size will
312 * remain 1.0, satisfying the ES default value in the GS/TES case, and
313 * the VS case (1.0 works for "undefined"). Mesa sets the program point
314 * mode flag to always-enabled in ES, so we can safely check that, and
315 * it'll be ignored for ES.
