WOW this is a huge improvement, I've always had small zooming issues but this works very well, nice work! It's even stable - zooming in and out repeatedly on the same pixel preserves that pixel position exactly <3

Zooming to cursor is one of the features we implemented in OpenLoco early on. The implementation is way more complicated than necessary, though, using land surfaces tiles as intermediaries. This PR removes this, and instead uses the viewport position relative to the mouse cursor to offset the new zoom level.
For completeness: this is an adaptation of OpenRCT2/OpenRCT2#25042
