<div>
<pre>Currently we use a hardcoded coverAreaMultiplier value of 2 in the TiledBackingStore, which means that the area we fill with tiles has up to 2 times the size of the visible area. While this is nice to make scrolling smoother, we are using more memory than needed to render the visible contents of layers (1 extra MB per tile).
When we are in memory pressure situation, we can reduce that value to use less tiles and improve the memory consumption.</pre>
