423 * taken from the (potentially clipped) shader built-in gl_PointSize
426 * * the geometry shader, if active;
427 * * the tessellation evaluation shader, if active and no
428 * geometry shader is active;
429 * * the vertex shader, otherwise
431 * and clamped to the implementation-dependent point size range. If
432 * the value written to gl_PointSize is less than or equal to zero,
433 * or if no value was written to gl_PointSize, results are undefined.
434 * If program point size mode is disabled, the derived point size is
435 * specified with the command
437 * void PointSize(float size);
439 * size specifies the requested size of a point. The default value
442 * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
443 * OES_tessellation_point_size specifications. To summarize: if the last
444 * stage before rasterization is a GS or TES, then use gl_PointSize from
445 * the shader if written. Otherwise, use 1.0. If the last stage is a
446 * vertex shader, use gl_PointSize, or it is undefined.
448 * We can combine these rules into a single condition for both APIs.
449 * Using the state point size when the last shader stage doesn't write
450 * gl_PointSize satisfies GL's requirements, as it's undefined. Because
451 * ES doesn't have a PointSize() command, the state point size will
452 * remain 1.0, satisfying the ES default value in the GS/TES case, and
453 * the VS case (1.0 works for "undefined"). Mesa sets the program point
454 * mode flag to always-enabled in ES, so we can safely check that, and
455 * it'll be ignored for ES.
