The GHOST_DisplayManager and its implementations are for the most part unmaintained and almost completely unused in all backends. To clean things up, and avoid any confusion about how displays are handled in each respective GHOST backend, this PR completely removes the GHOST Display Manager, and move the few remaining logic it still held directly to the corresponding backends. The backends that were modified (apart from removing the display manager initialization call from their init) are: - Win32: `GHOST_SystemWin32::getNumDisplays()` was calling `m_displayManager->getNumDisplays`, the underlying system metric call (`GetSystemMetrics(SM_CMONITORS)`) was substituted in place. - SDL: `GHOST_SystemSDL::createWindow` was calling `GHOST_DisplayManagerSDL::getCurrentDisplayModeSDL` which returned its `m_mode` data member by reference. Since none of the `GHOST_DisplayManagerSDL` member function that modified this data member were ever called, the variable `memset` initialization call was substituted in place from the `DisplayManagerSDL` constructor Pull Request: https://projects.blender.org/blender/blender/pulls/138066
