Trees and banners no longer disappear at the edges of wide screens.
- The stage is culled for the view's own horizontal angle. The game draws the sectors under a 90-degree triangle from the camera, while the port's views are wider on screens wider than 4:3, which keep the vertical view: at 21:9 trees and banners near the left and right edges went missing, and at 16:10 the chase camera already sees about 91.5 degrees. The triangle now opens to the angle of each view, split screen and the mirrored view included; views of 90 degrees or less are culled as before. Thanks to @mpietrowiak for finding it, the video and the fix in #13.
- The 2D layout arithmetic of the HUD, the menus and the scaled sprites follows the port's x87 single-precision conventions; the menus draw the same.
Tested locally on Linux i686 and x86-64: the unit tests, including a 21:9 case of the culling test, and the runtime scenarios. Release packages are built and tested by GitHub Actions for each supported platform.
