engine.c: add bound-check assert failing for sprites in m32's textured 2D mode.

Also, disable drawing sprites in that mode for now.

Mapster32: functionality to rotate or scale RShift-highlighted stuff smoothly.

This is done by pressing LShift and
 - holding down the left mouse button for scaling, or
 - the right mouse button for rotating the highlighted walls/sprites
with respect to a pivot point determined as the center of the bounding box of
all highlighted points.

Note that scaling sectors isn't that easy and the current functionality is very
rudimentary: there's no z scaling, no xrepeat correction, and sprites aren't
touched expect for their position.  The user is responsible to maintain map
consistency, for example to prevent wall-lines of the same sector crossing
each other.

Mapster32: when looking for matching wall in 2nd pt. ins., don't skip gray nextwalls.

This fixes a bug where it's not possible to split a sector under certain
circumstances, reported by Micky C here:

Also, don't allow zero in various 'F functions: Resize selection and
Global {shade, visibility} divide.
