<p>
Returns a render target's texture handle.
</p>
<pre>
HTEXTURE Target_GetTexture(
HTARGET <i><b>target</b></i>
);
</pre>
<h2>Parameters</h2>
<dl>
<dt><i>target</i>
<dd>Handle of the render target which texture handle will be returned.
</dl>
<h2>Return value</h2>
<p>
Returns the render target's texture handle.
</p>
<h2>Remarks</h2>
<p>
You may use the returned texture for rendering to screen or other render targets.
<br><br>
<b>DON'T</b> delete the textures obtained with <b>Target_GetTexture</b> call!
The results are unpredictable. A render target's texture is deleted
automatically during render target deletion.
<br><br>
The texture handle, returned by <b>Target_GetTexture</b> may change when
the application loses focus. So, obtain the handle every time you need it.
If you want to use cached handles you have to update them in your focus gain
function (see below).
<br><br>
Render targets' content is lost when the application loses focus.
If you render a texture each frame this is not a problem.
But if you render it once, at startup - you must rerender it when the
application gains focus. To do this - write a focus gain function
and attach it by setting
<a href="hgeconst_systemstate.html#HGE_FOCUSGAINFUNC">HGE_FOCUSGAINFUNC</a> system state.
