1. Fixed emboss bug in grd lines displaying model.
2. Grd line exceedes screen problem fix.
3. New rendering model - ray casted shadows and appropiate button to
set 'on' this option. Note that is non real time model, especially when
complex object is computed. I took effort to introduce accelerating
structure - AABB (Axis Aligned Bounding Boxes).. but it is disabled
for now - seems to work incorrect(slow).

View3ds 0.073 - may 2021
1. I introduced procedure for searching nonredundand edges.

What's new?
1. Fixed emboss bug in grd lines displaying model.
2. Grd line exceedes screen problem fix.
3. New rendering model - ray casted shadows and appropiate button to
set 'on' this option. Note that is non real time model, especially when

structure - AABB (Axis Aligned Bounding Boxes).. but it is disabled
for now - seems to work incorrect(slow).
1. Detecting manifold chunks procedure based on kind of sorted pivot
table. Chunks are counted and this number displayed.
2. New calculating normal vectors proc that use some data produced
by new chunks routine. Now big object loading is fast. I load object that
contains ~500000 vertices, ~700000 faces and ~2000 0000 unique edges
in few seconds on i5 2cond gen. Earlier such objects calculating was
rather above time limits.
3. On http://board.flatassembler.net occasionaly there are some disccusions
about optimizing. Some clever people, wich skills and competence I trust,
claims - for CPU's manufactured last ~15 years size of code is crucial
for speed. (Better utilize CPU cache).
So I wrote some 'movsd' mnemonics instead 'mov [edi],sth'; 'loop' instead
'dec ecx,jnz sth'. Moreover I come back to init some local varibles
by 'push' (flat_cat.inc). I took effort to change divisions to
multiplications two_tex.inc (works ok in fpu only Ext = NON mode and
of course in Ext = SSE3 mode), grd_tex.inc (single line not parallel
muls, whole drawing routine 4 divs instead 27 divisions),
bump_tex.inc - 3 divs in SSE2 mode.s See sources for details.
4. Editor button allows now editing by vertex all above 65535 vert objects.
