Light Speed! is an OpenGL-based program which illustrates the effects of
special relativity on the appearance of moving objects. When an object
accelerates past a few million meters per second, these effects begin to
grow noticeable, becoming more and more pronounced as the speed of light
is approached. These relativistic effects are viewpoint-dependent, and
include shifts in length, object hue, brightness and shape.
The moving object is, by default, a geometric lattice. 3D Studio and
LightWave 3D objects may be imported as well. Best of all, the simulator
is completely interactive, rendering the exotic distortions in real-time!

- changed build dependency from ftgl-dev to libftgl-dev (Closes: #485799)
- changed build dependency from libtiff4-dev to libtiff-dev
(preparation for switching to libtiff5 in Debian Jessie)
- added build dependency from autotools-dev
- added ${misc:Depends} to list of dependencies

ttf-bitstream-vera which is going to be removed from the repository
(Closes: #461272)

But build with libpng version 1.5.10 now impossible because
`pkg-config --cflags gtk+-2.0` returns error:
"Package 'libpng12', required by 'GdkPixbuf', not found"
