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