AI Summary: Implement a `map_geo_to_screen` function in the Galileo Rust library to complement the existing `screen_to_map_geo` function. This function should convert geographical coordinates to screen coordinates, providing a symmetrical pair of coordinate transformation functions.

AI Summary: Debug and fix a bug in the Galileo GIS rendering library where dragging an egui window unexpectedly moves the rendered map. This involves investigating the interaction between the egui window's drag events and the map's input handling within the Galileo library.

AI Summary: Implement a `map_to_screen` function in the Galileo GIS rendering library, mirroring the existing `screen_to_map` functionality. This function should take map coordinates as input and return corresponding screen coordinates.

AI Summary: Implement support for transparent images in `ImagePointSymbol` within the Galileo GIS rendering library, addressing an issue where images with backgrounds cause the map to appear white. Additionally, explore and potentially implement the ability to add rotation to the symbol.
