<h1>dlangui.graphics.resources</h1>
<!-- Generated by Ddoc from src\dlangui\graphics\resources.d -->
This module contains resource management and drawables implementation.
<br><br>
imageCache is RAM cache of decoded images (as DrawBuf).
<br><br>
drawableCache is cache of Drawables.
<br><br>
Supports nine-patch PNG images in .9.png files (like in Android).
<br><br>
Supports state drawables using XML files similar to ones in Android.
