WARD: WARD 'Aint Really for Drawing
No-nonsense infinite whiteboard, in the [suckless tradition](https://suckless.org/).
#### This lacks:
- multiple types of brushes.
- layers.
- save/load.
- custom palettes
- ... custom anything, really.
- mouse support.
#### This features:
- [x] Rock solid framerate.
- [x] Infinite undo/redo.
- [x] infinite whiteboard with panning.
- [x] Wacom tablet pressure sensitive drawing.
- [x] quick minimap view to view the entire whiteboard at a glance.
- [x] Not written using web tech: ~800 lines of readable c++ code.
- [x] grid background
- [ ] Draw points with a fixed time lag, then interpolate thickness of the line
from 0 to how wide it should be, offset from the time lag.
- [ ] Take a rolling average both backwards and fowards.
#### shortcuts:
- `Q`: undo
- `W`: redo
- `E`: toggle `E` raser
- `R`: `R` otate to next color.
- lower wacom button + drag: pan.
- upper wacom button: toggle overview. Tap to move to a location in the overview.
Tap upper button in overview mode to quit overview without moving.
- Color selection: hover pointer over color in color pot in color palette at bottom row.
- Eraser selection: hover pointer over eraser in color palette at bottom left.
The code uses:
- the [EasyTab](https://github.com/ApoorvaJ/EasyTab) library to work with Wacom tablets.
- The [Milton project](https://github.com/serge-rgb/milton) as heavy reference on how to work with tablets.
- [SDL2](https://www.libsdl.org/) for rendering.
- [Cairo-gl](https://www.cairographics.org/manual/cairo-cairo-t.html) for anti aliased vector graphics.
- [Spatial hashing](http://www.cs.ucf.edu/~jmesit/publications/scsc%202005.pdf) to quickly add and delete brush strokes.
- Lazy repainting of the entire frame upon change..
- Wishes to use [FastUIDraw](https://github.com/intel/fastuidraw) for an even faster backend than cairo.
