17387	NegativeArraySizeException at ImageWarp.warp	c933103@…	team	"==== What steps will reproduce the problem?
1. Use polar coordinate system
2. Navigate around

==== What is the expected result?
Display a map in polar projection
==== What happens instead?
a black hole around center that cannot load tiles and high computational resource consumption that doesn't seems to yield proper result and crash
==== Please provide any additional information below. Attach a screenshot if possible.
