Added a Magnifier. This can also be called a ‘Fat Pixel Editor’. This allows for detailed pixel editing. The mouse wheel can be used to set the size of the pixels (16 to 48). The idea is that editing at this scale is different than editing at a larger scale (this is, potentially, much more than the 300% max for canvas zoom). At the moment one can set colors of individual pixels but a number of ‘tools’ will be added to this feature – tools that are tailored to editing at this scale.
I thought about just allowing the zoom to go beyond 300% but decided that the benefits of changing the UX at that point was important.
