<h1>vertex_argb</h1>
<p>This function will set the <a class="tooltip" title="This is an anacronym for Alpha, Red, Green, Blue, and is used to refer to the colour components specified as a hexadecimal value, eg: #FF53E270, where each set of two digits represents a single component. Breaking down the ARGB example above gives us the following component values: Alpha(FF), Red(53), Green(E2) and Blue(70). ">ARGB</a> values for the vertex currently being defined for the custom primitive. You supply the buffer to write the data into as well as the red, green, blue and alpha values
that you wish to use as a single 32-bit unsigned integer - alpha sample in the highest 8 bits, followed by the red sample, green sample and finally the blue sample in the lowest 8 bits. You can use hex notation ($AARRGGBB) a real number or use any
of the <tt>make_colour_*()</tt> functions to define the colour value.</p>
