Previously we enabled/disabled the input system each frame, depending on the state of the ImGui windows. This commit changes the behavior into only enabling/disabling when the menu's are closed (either through the keyboard or the close button).
I added a simple callback to ImGui::Begin which will be called when the close button on the ImGui panel is pressed and the callback pointer isn't nullptr, this was required as there was otherwise no way to determine when the close button was clicked.
Upgrade includes all the modifications we brought to the library (SetWindowScrollX/Y, autocaret end, mouse state adjustments for game, highlight around input selection, hotkeys, etc..).
* Fixed click-through parent window.
* Keep selection position when lines get cleared.
* Keep cursor position when lines get cleared.
* Ensure cursor visibility when dragging cursor outside rect.
* Falter free scrolling in autocomplete window.
* Falter free scrolling in logging window (window no longer stutters when lines get cleared).
* Codebase restructured to SourceSDK codebase style and .cpp/.h assertion paths in the game executable.
* Document most functions with valve style 'Purpose' blocks.
* Rename variables to match the rest of the codebase and Valve's naming convention.
* Dedicated DLL and the SDKLauncher now share the same codebase as the DevSDK.
* Obtain globals or pointers directly instead of waiting for runtime initialized data.
* Dynamically search for all functions and globals (this doesn't count for dedicated yet!).
* Initialize most in-SDK variables.
* Move certain prints and other utilities under ConVars to reduce verbosity and increase performance.
* Print all pattern scan results through a virtual function to make it easier to add and debug new patterns in the future.
* Type global var pointers appropriately if class or type is known and implemented.
* Forward declare 'CClient' class to avoid having 2 'g_pClient' copies.
* Add IDA's pseudo definitions for easier prototyping with decompiled assembly code.
* RPAK decompress Command callback implementation.
* Load decompressed RPaks from 'paks\Win32\' overriding the ones in 'paks\Win64\' (the decompress callback will automatically fix the header and write it to 'paks\Win32\').
* VPK decompress Command callback implementation.
* Move CRC32 ands Adler32 to implementation files.
* Server will print out more details about the connecting client.
* Upgrade ImGui lib to v1.86.
* Don't compile id3dx.h for dedicated.
* Don't compile id3dx.cpp for dedicated
* Implement DevMsg print function allowing to print information to the in-game VGUI/RUI console overlay, ImGui console overlay and the external windows console
* Fixed bug where the Error function would not properly terminate the process when an error is called. This caused access violations for critical/non-recoverable errors.
* Fixed bug where the game would crash if the console or server browser was enabled while the game was still starting up.
* Several bug fixes for the dedicated server (warning: dedicated is still considered work-in-progress!).
