bgiGetGizmoText

Gets the text content of a gizmo control. Searches gizmoMap for the gizmo ID. For status bars (GIZMO_STATUSBAR), sends SB_GETTEXTLENGTH to get length (LOWORD), allocates buffer, sends SB_GETTEXT for part 0, stores in static string, returns c_str(). For other gizmos, calls GetWindowTextLength to get length, allocates buffer, calls GetWindowTextA to retrieve text, stores in static string, returns c_str(). Returns empty string if zero length or gizmo not found.

This function retrieves current text from controls. Works with buttons, labels, textboxes, windows, status bars, and text-capable controls. Status bars require SB_GETTEXT message (part 0). Uses static string for return value - copy immediately if needed across multiple calls. Returns actual window text (not stored title). Use for reading user input, validating data, or querying control states.
