[OpenJDK Rasterizer] Marlin #4

[Jim Graham]

Hi Laurent,

I've been looking at it a little lately.

One thing that occurred to me is that the 2 strategies - RLE vs 
uncompressed - might be easier to follow and manage if they were broken 
out into separate classes:

MarlinCache
+--- MarlinRLECache
+--- MarlinUncompressedCache
