This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
- Iteration still going on after scan finished
- Comparing milliseconds with seconds
- Potential imprecision due to accumulating milliseconds (iteration could take fewer than 1ms)
- Folders to scan not cleared when a new search starts
- FileAccess was accessed null (remains of GDScript port)
- `_current_file` wasn't going up correctly in case a scanned directory had no subdirectories
- Paths stored in `_files_to_scan` were not full paths
