* Making terrain query resolution a single float instead of a Vector2 Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Keeping the concept of different x/y step sizes in region queries since that may be useful and is separate from query resolution. Also keeping the concept of different x/y step sizes in physics since that's independent of the terrain gem. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Formatting cleanups Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * A few more minor cleanups Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Added support to convert serialized Vector2 query resolution to a single float. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Switch ray intersection check back to using separate values for x and y resolution Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Fixing new unit tests added to use float query resolution. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Updating automated test Signed-off-by: Ken Pruiksma <pruiksma@amazon.com>
