| * DC. If we here create a larger image, draw in to it and have |
| * that memory DC then lose the image resolution only to scale it |
| * back up again when sending to a printer it will look really bad. |
| * So, is this is either a printer DC or an enhanced meta file DC ? |
| * Scale only if it is. Use a 4x scale factor, partly since for |
| * an enhanced meta file we don't know anything about the |
| * real resolution of the destination. |
| * |
| * For a printer DC we could probably derive the scale factor to use |
| * by querying LOGPIXELSX/Y, and dividing that by the screen |
| * resolution (typically 96 dpi or 120 dpi) but that would typically |
| * make for even bigger output for marginal extra quality. |
| * But for enhanced meta file we don't know anything about the |
| * real resolution of the destination so |
