PixelPaint: Propagate errors in {flip,crop,rotate,resize} functions

Browse source 
We now propagate errors when using the {Layer,Image}::flip(),
{Layer,Image}::crop(), {Layer,Image}::rotate() and
{Layer,Image}::resize() functions.

We handle these errors by show an error DialogBox with the error's
message.

This removes 8 FIXMEs:))
