Detailed Description

ImGui panel that streams live screenshots from a running Mesen2 emulator via socket and displays them as a GPU texture preview.

The panel polls the Mesen2 Screenshot() API at a configurable rate, decodes the base64-encoded PNG response to RGBA pixels, uploads them to an SDL texture, and renders the result with ImGui::Image().
