They weren't implemented in Lua itself. There's an explanation as to why this is on the main Lua site.
It'd be good if the image.draw(x,y,srcx,srcy,srcwidth,srcheight) worked on orientations other than the default 0 (landscape). The function doesn't use the source x,y position from which the image is supposed to draw and instead uses 0,0 within the image. So if you wanted to draw a part of an image in portrait view it will always give you a piece from the top left corner of size srcwidth, swrcheight instead of from the position within the image of srcx,srcy.
