0.6.3-alpha

Fixes a red, cloudless sky in the Windows build of 0.6.2-alpha. Windows, Linux and macOS builds are attached once the release workflows finish.

The Windows sky

The colours the sky is drawn from sit in a packed palette: nine slots of three bytes, two bytes behind a flag. Keeping them one-byte aligned relies on an attribute the Windows compiler does not honour, so on that build alone the slots started four bytes in rather than two, and every colour was read two bytes late. Red took the blue channel, green took the padding byte, and the sky came out red with no cloud.

Measured on Windows with a PAL disc: the sky read 83,0,2 where the palette holds 14,30,78. The same build on the same machine now reads 2,67,130.

The layout is asserted at compile time, so a toolchain that moves it again fails the build rather than shipping a wrong colour.

This only ever affected Windows. The macOS and Linux builds of 0.6.2-alpha draw the sky correctly, and so does the classic renderer on Windows, which draws most of its sky from a texture rather than from the palette.

Also since 0.6.2-alpha

• The split times a replaying ghost draws are anchored to the edges of a widescreen picture, so in time attack the times on the left and the total on the right no longer sit in the middle while their labels move out.
• The ranking screen in time attack can be opened; it used to close itself on the frame it opened.
• Three copies of the track visibility rule, two copies of the split-time drawing, two copies of a curve's arc measurement and two identical CD play routines are each one piece of code now, with tests where there were none.
