Git revision is generating on build time (not on configure time). In case of uncommited changes this revision will be marked as "dirty". If cmake cannot retrieve revision from git history (i.e. from packaged source code), cmake will attempt to read "git-hash.txt" from `PROJECT_SOURCE_DIR` (it will be generated on build time; after implementing packaging workflow it can be reworked).
Reworked main screen and console output to display proper version.
Version project now is 1.5.0 as previous PATCH value (500) was intended to be D3_RELEASE_BUILD_NO, autogenerated on compile time. As we switched to GIT_HASH, D3_RELEASE_BUILD_NO now useless.
CMAKE_BUILD_TYPE must be set CACHE before project() to take effect
general best practice rather than modifying CMake internal variables
is to use add_compile_options with genex
At this point, all remaining references to `MACINTOSH` are either part
of multi-value conditionals that `unifdef` was unable to determine the
final value for, or a `#define`, or a comment. I manually go through the
files with a Ctrl+Shift+F search (ignoring legacy/, to preserve useful
historic knowledge) and clean up each usage.
As part of that search, I discovered `lib/mac/` which I deleted wholly.
Test Plan:
On Mac, build both Debug and Release
```
cmake --build --preset mac --config Debug
cmake --build --preset mac --config Release
```
The MACINTOSH define refers to MacOS Classic (not OS X) which we do not
plan to support. Rather than carry the cruft forever, let's delete it.
NOTE: legacy/ is unused but we're keeping it around, so MACINTOSH uses
there are left alone.
Process used for this commit:
```
git rm -r mac
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" \) \
-exec unifdef -UMACINTOSH -o {} {} \;
git restore legacy
git add .
```
Test Plan:
On Mac, build both Debug and Release
```
cmake --build --preset mac --config Debug
cmake --build --preset mac --config Release
```
None of these sources are referenced, either directly or indirectly,
in any CMakeLists.txt file.
NOTE: All of legacy/ is unused, but we're keeping it around.

**NOTE: THIS MUST BE DONE ON A CASE-SENSITIVE FILESYSTEM**. There are a
few instances of differing-in-case-only (hogmaker vs HogMaker, etc) that
will catch you out otherwise.

# names. So, delete the ${SCRIPT}.cpp filename...

# find those, with another subshell concatenation:

# Split on spaces, take the second field
cut -d ' ' -f 2 |

# *** 6: FINALLY, sort and dedupe the output into a file.

# Now that we know all the used source files, we need to find all of
# the source files in the repo, and delete them if they do not appear
# in the used_srcs list.

# find outputs the relative path, we want to operate on just filename
basename $SRC |

# -q means be quiet, do not print the match (so this doesn't spam)
# -x means match the entire line (so macfile.cpp doesn't sneak thru
# via cfile.cpp)
# -F means treat the lines patterns as fixed (not regexp)
# -f means load patterns from the given file
grep -qxFf used_srcs ||
# If the grep command *fails*, then the file is not in the list.
# Bash performs logic short-circuiting, so we can use logical-OR
git rm $SRC;

```
Test Plan:
On all three of `[win, mac, linux]`:
```
cmake --preset <platform>
cmake --build --preset <platform> --config Debug
cmake --build --preset <platform> --config Release
```
Any --foo -foo and +foo is now accepted on any OS. Also enables
single char arguments like -f everywhere. Previously -foo had
to be passed as --foo on Linux, and macOS behaved like Windows.
Cast the rotation values to a short before assigning to the tangles
struct to avoid the FCVTZU instruction which strips the negative sign
from kicking in.
