#11 inverted normal maps ( in Blender )

[dotblend]

when using an exported normal map in Blender, the light behaviour is inverted (X axis)
not a big deal, but it adds a step (X mirror the png file or -scaleX in Blender).
I don't know if there's a normal map standard, but maybe two 'X flip' and Y flip' checkboxes could be added in the export normal map window.
