Henrik RydgårdandClaude Opus 5 27ca0f80fc sceFont: let glyphs draw past bytesPerLine, like the hardware does ...

SetFontPixel refused to write any pixel whose x fell outside
bytesPerLine, so a glyph drawn into a buffer with a bytesPerLine
narrower than its rows came out mostly blank. The hardware doesn't
bound it that way - it works out an address and writes, so the rows
overlap and the glyph smears across them. The declared bufWidth and
bufHeight, plus the address check, are what keep it in bounds.

Cache invalidation now covers the wider of bytesPerLine * bufHeight and
where the last row actually ends, since those are no longer the same
thing when the rows overlap.

Fixes font/charglyphimage and font/charglyphimageclip, moved from
tests_next to tests_good. The other font tests are unaffected, so
whatever ails them is something else.
