+<p>This driver release supports X screens with screen depths of 30
+bits per pixel (10 bits per color component). This provides about 1
+billion possible colors, allowing for higher color precision and
+smoother gradients.</p>
+<p>When displaying a depth 30 image, the color data may be dithered
+to lower bit depths, depending on the capabilities of the display
+device and how it is connected to the GPU. Some devices connected
+via analog VGA or DisplayPort can display the full 10 bit range of
+colors. Devices connected via DVI or HDMI, as well as laptop
+internal panels connected via LVDS, will be dithered to 8 or 6 bits
+per pixel.</p>
+<p>To work reliably, depth 30 requires pixman 0.11.6 or higher.</p>
+<p>In addition to the above software requirements, many X
+applications and toolkits do not understand depth 30 visuals as of
+this writing. Some programs may work correctly, some may work but
+display incorrect colors, and some may simply fail to run. In
+particular, many OpenGL applications request 8 bits of alpha when
+searching for FBConfigs. Since depth 30 visuals have only 2 bits of
+alpha, no suitable FBConfigs will be found and such applications
+will fail to start.</p>
