All window coordinates behave as follows: |
| 50 |
- the origin is assumed to be in the top left, so ensure that |
| 51 |
your templates have this to avoid problems |
| 52 |
- x coordinates are 0 at the origin and increase across the window |
| 53 |
- y coordinates are 0 at the origin and increase down the window |
| 54 |
- scroll offsets are also always positive |
| 55 |
|
| 56 |
Coordinates are usually in os units. However, the document classes |
| 57 |
and fonts use millipoints. At 100%, 400 millipoints = 1 os unit. |
| 58 |
Font sizes are in 1/16 points. |
