Setup a linear gradient, and a block entity which uses the gradient for its fillStyle value
Check that we can successfully manipulate the gradient's start and end coordinates
Check that we can successfully manipulate the palettes's start and end cursors
Check that we can dynamically add and remove color stops
Check that we can ease the gradient, including user-defined easing algorithms
Check that when precision is set to 0, gradient uses the linear easing
Check that when cyclePalette is set to true and the palette's end value is smaller than its start value, the gradient draws itself by going through the 0/999 endpoints
