Allow to create raster layer programmatically from 2D array
|Pull Request or Patch supplied:||No||Resolution:|
Since it is possible to create vector layers programmatically via the 'memory' provider, the same should be possible for raster layers. I'm not talking about support for taking a handle to a GDAL layer (although that would be awesome as well). I know that raster layers can be huge so this would be a concern of plugins to decide whether they want to use this simple keep-the-whole-layer-in-memory approach or write a custom plugin layer class, which is often a very non-trivial thing to do.
