Add pan and zoom toolbar handling to 3D Axes (Replaces PR#22614) (matplotlib#23449)
* ENH: Add pan and zoom toolbar handling to 3D Axes 1) This moves the pan logic that was already in the mouse move handler into the "drag_pan" method to make it available from the toolbar. 2) This expands upon the panning logic to enable a zoom-to-box feature. The zoom-to-box is done relative to the Axes, so it shrinks/expands the box as a fraction of each delta, from lower-left Axes to lower-left zoom-box. Thus, it tries to handle non-centered zooms, which adds more cases to handle versus the current right-click zoom only scaling from the center of the projection. * Rewrite zooming with bounding box * Rewrite 3d panning to work with a roll angle * Whats new for zoom and pan buttons * Make pan button configurable * Do not jump when zooming and mouse goes over other subplot * Rework zooming for 3d plots * Handle x/y lock when zooming and panning * Update tests * Docstrings * Dont assume a scale_z * Limit zoom box * Test zoom pan key modifiers * Save some calculation by saving view axes * Deprecation warnings for Axes3D.eye, .vvec * Remove Axes3D._prepare_view_from_bbox for now * Comments and docstrings * Switch from uvn to uvw * Save aspect to axes * Constrain zooming with mouse when one of the equal aspect ratios is set * Cleanup * Cleanup * Consolidate finding equal aspect axis indices * linting * More intuitive scaling * Box zoom keeps existing aspect ratios * Linting * Code review comments * Revert parameters for view_transformation * Fix new 3d pan/zoom view going on view stack twice * Better clipping * Test 3d toolbar navigation * Privatize helper functions * Deprecations * Code review changes * Deprecation note * Undeprecate proj3d.view_transformation * Undeprecate proj3d.view_transformation * Update doc/api/next_api_changes/deprecations/23449-SS.rst Co-authored-by: Greg Lucas <greg.m.lucas@gmail.com> Co-authored-by: Scott Shambaugh <scottshambaugh@users.noreply.github.com> Co-authored-by: Oscar Gustafsson <oscar.gustafsson@gmail.com>

3D plot pan and zoom buttons
2+
----------------------------
3+
4+
The pan and zoom buttons in the toolbar of 3D plots are now enabled.
5+
Unselect both to rotate the plot. When the zoom button is pressed,
6+
zoom in by using the left mouse button to draw a bounding box, and
7+
out by using the right mouse button to draw the box. When zooming a
8+
3D plot, the current view aspect ratios are kept fixed.
