+all of pugl's built-in values begin with a <code>.</code> to distinguish
+them from your widgets.
+here they all are.
+below, <code>float</code> refers to a plain old number,
+<code>vec2</code> is a 2-component vector, etc.
+
+<table>
+<tbody>
+<tr><th>built‑in</th><th>type</th><th>description</th></tr>
+<tr><td><code>.pos</code></td><td><code>vec2</code><td>the position of the pixel, with (−1, −1) being the bottom-left corner, and (+1, +1) being the top-right corner.</td></tr>
+<tr><td><code>.pos01</code></td><td><code>vec2</code><td>the position of the pixel, with (0, 0) being the bottom-left corner, and (+1, +1) being the top-right corner.</td></tr>
+<tr><td><code>.time</code></td><td><code>float</code><td>the amount of time that has passed (wraps around every hour to prevent imprecision issues).</td></tr>
+<tr><td><code>.mouse</code></td><td><code>vec2</code><td>the position of the mouse ranging from (−1, −1) to (+1, +1).</td></tr>
+<tr><td><code>.mouse01</code></td><td><code>vec2</code><td>the position of the mouse ranging from (0, 0) to (+1, +1).</td></tr>
+<tr><td><code>.pi</code></td><td><code>float</code><td>π (3.1415…).</td></tr>
