WINTERMUTE: Fix slider bugs in several games
There is a bug introduced in WME Lite. Testcase: 1. Download https://github.com/lolbot-iichan/wme_testsuite/tree/master/slider_test/packages 2. Download https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/wmelite/wmelite_10_win.zip 3a. Run game.exe -> Slider moves with the mouse while it is pressed and released when mouse is released 3b. Run wmelite.exe -> Slider is never released 3c. Run ScummVM -> Slider is never released Related bugs: https://bugs.scummvm.org/ticket/6567 https://bugs.scummvm.org/ticket/9861 Reason: slider is a button object that changes it's X until "LeftRelease" event is revieved and breaks the endless loop. Sample code: https://github.com/lolbot-iichan/wme_testsuite/blob/master/slider_test/data/interface/system/speechvolume.script However, WME Lite does not send "LeftRelease" events to any objects, if Game object can handle such event, even is game is frozen and UI is shown. Original code: https://github.com/lolbot-iichan/Wintermute-Engine/blob/master/src/engine_core/wme_ad/AdGame.cpp#L2218 Changed in WME Lite: https://github.com/lolbot-iichan/wmelite/blob/master/src/AdGame.cpp#L2120 This behaviour was introduced in SVN period of wmelite, I believe it was made on purpose for handling some iOS scenarios at commit #37 mentioned on page https://code.google.com/archive/p/wmelite/source/default/commits My proposal is to mark iOS apps as WME_LITE and fill exact WME_1_X_X/WME_LITE versions for all known games. WME_1_X_X can be seen by right-clicking on main executable and seems to be non-empty for almost all existing WME games.
