Weight cursor position when zooming

[brenocq]

@epezent feedback in #24

ImPlot weights zooming depending on where the cursor is in location horizontally/vertically in the plot; I don't think that is happening in ImPlot3D

It is not happening! I will take a look into the ImPlot implementation to also have it with the ImPlot3D.

I just finished implementing this feature and it can be tested in the dev branch (8352ea8). When the cursor is over a plane/axis, the cursor position is weighted when zooming. If the cursor is outside the plot box, the zoom occurs around the center (the same behavior as before).

This is way better! Thanks for the feedback @epezent
