<p>
Creates a render target.
</p>
<pre>
HTARGET Target_Create(
int <i><b>width</b></i>,
int <i><b>height</b></i>,
bool <i><b>zbuffer</b></i>
);
</pre>
<h2>Parameters</h2>
<dl>
<dt><i>width</i>
<dd>Width of the render target to be created.
<dt><i>height</i>
<dd>Height of the render target to be created.
<dt><i>zbuffer</i>
<dd>If <b>true</b>, a Z-buffer will be created and used for rendering to the render target.
</dl>
<h2>Return value</h2>
<p>
If successful, returns the render target handle to use with
<a href="hgefunc_gfxbeginscene.html">Gfx_BeginScene</a>.
Otherwise returns 0.
</p>
<h2>Remarks</h2>
<p>
The render target dimensions must be a power of 2. If this condition isn't met,
the requested dimensions are automatically adjusted to the closest power of 2
dimensions, bigger than the requested ones.
<br><br>
Render targets support alpha channel in 32-bit video modes only, in 16-bit video modes
render targets are always opaque. You could read <a href="hgeconst_systemstate.html#HGE_SCREENBPP">HGE_SCREENBPP</a>
system state to discover in what video mode <b>HGE</b> is currently running.
<br><br>
If the function fails, you may obtain error message with <a href="hgefunc_systemgeterror.html">System_GetErrorMessage</a>
function. Also if <a href="hgeconst_systemstate.html#HGE_LOGFILE">HGE_LOGFILE</a> system state was set, the
error message is written to log.
<br><br>
When the render target isn't needed longer, you must delete it with
<a href="hgefunc_targetfree.html">Target_Free</a> function.
