This reverts commit 8990b66eed2f00253653e64c0ceb695c08a359b7.
Fix some map tool connections, followup to 59a6663 and 6609ca8
Remove invalid/unused anchor point expressions from simple fill data defined expression dialog
[FEATURE] Add 'shapeburst' fill style. Shapeburst fills implement a buffered gradient fill, where a gradient is drawn from the boundary of a polygon towards the polygon's centre. Configurable parameters include distance from the boundary to shade, use of color ramps or simple two color gradients, optional blurring of the fill and offsets.
More descriptive name for colour parameters in gradient and shapeburst fill data defined symbology dialog
Avoid multiple creation and destruction of arrays during calculation of distance transform in shapeburst fills
Add a slider for setting the shapeburst fill blur amount
Consider rasterScaleFactor during shapeburst fills
Limit resolution of symbol fills during composer previews to improve composer responsiveness
Merge pull request #1255 from Oslandia/atlas_signals

Atlas signals
better naming for messageEmitted/Discarded in maptools, followup 5bc5fdb 59a6663 and 6609ca8
use single signal for messageEmitted
show python errors in monospace
Fix gradient fills using color ramps not respecting symbol transparency
Add option to ignore interior polygon rings when calculating buffered shading for shapeburst fill mode (can be useful for eg ignoring islands when shading water bodies)
