Adding ability to have y-axis log scaling in 1D.

Adding the ability to have log scale y axis data in the 1D view. Adding new tick mark generator for log scale. Adding log scale test case. Adding straight line rendering test due to horizontal straight lines not being renderable (due to axis range being equal). This is fixed now during 1D paint with a valid bounds check. Fixing color mapper error that returns black when the data range is equal. Enabling 2D and 3D user annotations support, updating test cases.
