Was harmless but confused some sanity checks, also kinda makes sense
to be more verbose about what's going on there.

Fix 1px gap in regions drawn with region overlap

Fix T45240: New depsgraph ignores animation applied on the curve data

Fix T45238: New depsgraph flickers with the lattice modifier

Fix T45241: New depsgraph was lacking update of python drivers on time change

It's quite tricky to see if the driver actually depends on time or not,
so currently used approach when we'll be doing some extra updates.

This seems to correspond to how old depsgraph was dealing with this.

Fix T45239: New depsgraph does not work with IK pole target

Fix T45251 custom directory not taken into account for image proxies.

Fix for mistake in grid-snap patch

instead of just snapping the input values for translate.

Cleanup: transform grid snap round, not floor

Note that closest_point_on_mesh is in object space

Cleanup: use const for screen functions

Cleanup: move BLI_char_switch into BLI_string

Cleanup: use BLI_str prefix for BLI_replacestrN
