Is it possible to print to the Report window in the Info view? I wonder if it is currently possible to print or send messages to the Report window in the Info view? this would be quite useful sometimes.
We can always use an operator's report method. Running the following operator:

class RENDER_OT_test(bpy.types.Operator):
    bl_idname = 'render.oha_test'
    bl_label = 'Test'
    bl_options = {'REGISTER', 'UNDO'}

    def execute(self, context):
        self.report({'INFO'}, 'Printing report to Info window.')
        return {'FINISHED'}


prints this in the Info window:



The color depends on the type enum: INFO gets green, WARNING light red, and ERROR dark red. I don't see reference to any direct output to Info window, other than this method.
