<h2>Graphics related configuration settings</h3>
<ul>
<li>
<code>CONFIG_NXGRAPHICS</code>
Enables overall support for graphics library and NX
</li>
</ul>
<h3>NX configuration setting</h3>
<ul>
<li>
<code>CONFIG_NX_MULTIUSER</code>
Configures NX in multi-user mode
</li>
<li>
<code>CONFIG_NX_NPLANES</code>
Some YUV color formats requires support for multiple planes,
one for each color component. Unless you have such special
hardware, this value should be undefined or set to 1
</li>
<li>
<code>CONFIG_NXGLIB_DISABLE_1BPP</code>, <code>CONFIG_NXGLIB_DISABLE_2BPP</code>,
<code>CONFIG_NXGLIB_DISABLE_4BPP</code>, <code>CONFIG_NXGLIB_DISABLE_8BPP</code>
<code>CONFIG_NXGLIB_DISABLE_16BPP</code>, <code>CONFIG_NXGLIB_DISABLE_24BPP</code>, and
<code>CONFIG_NXGLIB_DISABLE_32BPP
NX supports a variety of pixel depths. You can save some
memory by disabling support for unused color depths.
</li>
<li>
<code>CONFIG_NXGL_PACKEDMSFIRST</code>
If a pixel depth of less than 8-bits is used, then NX needs
to know if the pixels pack from the MS to LS or from LS to MS
</li>
<li>
<code>CONFIG_NX_MOUSE</code>
Build in support for mouse input
</li>
<li>
<code>CONFIG_NX_KBD</code>
Build in support of keypad/keyboard input
</li>
</ul>
<h3>NX Multi-user only options</h3>
<ul>
<li>
<code>CONFIG_NX_BLOCKING</code>
Open the client message queues in blocking mode. In this case,
<code>nx_eventhandler()</code> will never return.
</li>
<li>
<code>CONFIG_NX_MXSERVERMSGS</code> and <code>CONFIG_NX_MXCLIENTMSGS</code>
Specifies the maximum number of messages that can fit in
the message queues. No additional resources are allocated, but
this can be set to prevent flooding of the client or server with
too many messages (<code>CONFIG_PREALLOC_MQ_MSGS</code> controls how many
messages are pre-allocated).
