Build 63

- Implemented font shadows alongside font outlines. A 2-pixel drop shadow is now the default.
- Changed the hint configuration in the author's configuration to a 6×6 hint grid. When a hint is selected, the same 6×6 hint grid is displayed over the zoomed area, in full screen.
- (Breaking change) Made hint cell size, font size, and border thickness independent of zoom level to prevent rounding issues and simplify the configuration.
```properties
# Old:
#hint2-2-mode.zoom.percent=5.0
#hint2-2-mode.zoom.center=last-selected-hint
#hint2-2-mode.hint.grid-cell-width=10
#hint2-2-mode.hint.grid-cell-height=15
#hint2-2-mode.hint.font-size=3.6
#hint2-2-mode.hint.box-border-thickness=0.2
# New:
hint2-2-mode.zoom.percent=5.0
hint2-2-mode.zoom.center=last-selected-hint
hint2-2-mode.hint.grid-cell-width=50
hint2-2-mode.hint.grid-cell-height=75
```
- (Breaking change) Renamed the two properties related to how hints are laid out:
```properties
# Old:
#hint1-mode.hint.subgrid-row-count=6
#hint1-mode.hint.subgrid-column-count=5
# New:
hint1-mode.hint.layout-row-count=6
hint1-mode.hint.layout-column-count=5
```
