Details

Browse source 
Gewijzigde functionaliteiten:
- Splits kleurplaten in kleur-, potlood- en bovenste inktlaag zodat contouren zichtbaar blijven.
- Versterk lijnen met een lichte contrastrand en donkere inkt, met behoud van de juiste overlappingen.
- Vernieuw werkvlak, gereedschappen en kleurenpalet voor een krachtiger grafische uitstraling.
- Voeg regressietests toe voor laagvolgorde en inktweergave.

Tests:
- npm test (201 geslaagd)
