Empty raster (for example coming from path with empty bound
rasterization, ...) drawing threw error.
This change prevent raster drawing in that case.
Closes#1320
Group selected color was applied differently to its bounds and position
depending on whether it had children or not when selected color was set.
This resulted in an unpredictable behaviour from a user point of view.
To change that:
- When `item.setSelectedColor()` is called, value is now always stored
in `item._style._values`, independently from the fact that item has
children or not.
- An helper method `compareCanvas()` is added to the test suite to allow
comparing selection rendering of a known working case to a failing one.
Two provided callbacks are executed in a dedicated `<canvas>`/`Project`
context and both results are compared with `resemble.js`.
Mouse interactions tests only passed in `gulp load` context.
This make sure that native event classes are used in built context.
This also remove the reference to `CanvasProvider` which is not
available in built context.
Fixes bug introduced in #1570
- Tests common mouse interactions scenarios to prevent regressions
when making changes. These tests are not run in node context.
- Prevent name collision between Javascript native classes and Paper.js
classes (Event and MouseEvent) by patching load.js.
- Uses a polyfill for MouseEvent which is missing in PhantomJS.
- Adds View._clearState() method and use it in tests to make sure that
each new test is started with a fresh state.
Bug happen when item is drawn after an empty symbol that should be drawn
in a separate canvas context (partial opacity or special blend mode).
As bounds are empty, symbol drawing process is interrupted but its
global matrix is not removed from the stack.
Closes#1561
When importing rasters after load if the image has a matrix with any translation/skew value
the image will calculate the wrong matrix after loading.
In order to correct this we append the translation rather than prepend so
that it happens in the correct order relative to the transformation.
