A wxPanel subclass that implements a fully clickable panel with mouse hover highlight and click feedback. The 'RBindBaseEvents' method recursively binds left-click events to all child windows, propagating clicks to the panel's own event handler. The panel also provides helper methods to recursively set foreground/background colours on children. The BtnPanel subclass adds a centered label. This component is self-contained (only dependency is wxWidgets) and could be extracted into a separate library for any wxWidgets application needing clickable panels with hover effects.

Exposes a single free function 'SteamImageToBitmap' that converts a Steam image ID (e.g., avatar) into a wxBitmap. It uses SteamUtils to get image dimensions and RGBA data, then copies the RGB bytes into a wxImage. This function encapsulates the conversion logic and is reusable in any wxWidgets application that works with Steam images, requiring only the SteamStuff global context.

Implements a queue-based inviter that processes a queue of SteamID64s one at a time, waiting for each invite result callback before proceeding. It uses a STEAM_CALLBACK to listen for RemotePlayInviteResult_t and pops the next invite after a successful or failed attempt. This pattern of sequential processing with callback-driven continuation is reusable for any scenario requiring rate-limited or sequential Steam operations without blocking the main thread.
