Make loading and "scaled zoom" tiles RGB_565 to save memory #368

Closed GoogleCodeExporter closed 8 years ago

Memory is a tight squeeze in osmdroid, so saving space is a good idea. It 
allows for bigger tile caches and more importantly it can cut down on GCs 
(which osmdroid produces a lot of).

So let's change the loading tile and all Bitmaps created by the rescaleCache() 
method from ARGB_8888 (32-bit) to RGB_565 (16-bit no alpha). It will produce 
smaller bitmaps and cause less GCs.

This revision was reverted by r1341 and issue 452. We no longer use 565 bitmaps.
