+ * Renders a text (<code>"centerText"</code>) with a given font height (<code>"centerTextHeight"</code>) in the center of the component and
+ * draws a label for each pin with a given font height (<code>"pinLabelHeight"</code>). The labels of pins to the left of a given x

+ * left. A margin (<code>"pinLabelMargin"</code>) is applied for pin label drawing.<br>
