An example of the File Dialog integrated within the ImGui Demo App
- Separate system for call and display
- Can use custom pane via function binding
- this pane can block the validation of the dialog
- can also display different things according to current filter and User Datas
- Support of Filter Coloring
- Multi Selection (ctrl/shift + click) :
- 0 => infinite
- 1 => one file (default)
- n => n files
- Compatible with MacOs, Linux, Win
- On Win version you can list Drives
- Support of Modal/Standard dialog type

You can define in OpenDialog call the count file you wan to select :
- 0 => inifnite
- 1 => one file only (default)
- n => n files only
See the define at the end of these funcs after path.
