Summary:
This PR replaces Core Graphics implementation with Core Animation for radial gradients. I found that
endPoints
for radial gradient type works differently than linear gradient type. TheendPoint.x
accounts for horizontal length andendPoint.y
accounts for vertical. This makes it possible to draw ellipse gradients. So we don't need the core graphics API anymore.Changelog:
[IOS] [CHANGED] - Optimised Radial Gradients.
Test Plan:
Non breaking change. Test Radial gradient example from RNTester. Compare results with web, android and iOS. Each platform should render the gradients identically.
