From 54aca22058e8f4daf999b37e5c5e6ddd8e67f811 Mon Sep 17 00:00:00 2001 From: Søren Sandmann Pedersen Date: Fri, 7 Dec 2012 19:43:53 -0500 Subject: demos/radial-test: Add zero-radius circles to demonstrate rendering bugs Add two new gradient columns, one where the start circle is has radius 0 and one where the end circle has radius 0. All the new gradients except for one are rendered with a bright dot in the middle. In most but not all cases this is incorrect.
