-// A class that emulates an IME for windowless plugins. A windowless plugin |
-// does not have a window. Therefore, we cannot attach an IME to a windowless |
-// plugin. To allow such windowless plugins to use IMEs without any changes to |
-// them, this class receives the IME data from a browser and patches IMM32 |
-// functions to return the IME data when a windowless plugin calls IMM32 |
-// functions. I would not Flash retrieves pointers to IMM32 functions with |
-// GetProcAddress(), this class also needs a hook to GetProcAddress() to |
-// dispatch IMM32 function calls from a plugin to this class as listed in the |
-// following snippet. |
-// |
-// FARPROC WINAPI GetProcAddressPatch(HMODULE module, LPCSTR name) { |
-// FARPROC* proc = WebPluginIMEWin::GetProcAddress(name); |

-// |
-// After we successfuly dispatch IMM32 calls from a plugin to this class, we |
-// need to update its IME data so the class can return it to the plugin through |
-// its IMM32 calls. To update the IME data, we call CompositionUpdated() or |
-// CompositionCompleted() BEFORE sending an IMM32 Window message to the plugin |
-// with a SendEvents() call as listed in the following snippet. (Plugins call |
-// IMM32 functions when it receives IMM32 window messages. We need to update the |
-// IME data of this class before sending IMM32 messages so the plugins can get |
-// the latest data.) |
