[smooth] Faster alternative line renderer.
This implementation renders the entire line segment at once without
subdividing it into scanlines. The main speed improvement comes from
reducing the number of divisions to just two per line segment, which
is a bare minimum to calculate cell coverage in a smooth rasterizer.
Notably, the progression from cell to cell does not itself require any
divisions at all. The speed improvement is more noticeable at larger
sizes.

[base] Fix a leak by broken sfnt-PS or resource fork (#46028).
open_face_from_buffer() frees passed buffer if valid font
is not found. But if copying to the buffer is failed,
the allocated buffer should be freed within the caller.
* src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free
the buffer `sfnt_ps' if an error caused before calling
open_face_from_buffer().
(Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if
an error caused before calling open_face_from_buffer();

[sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values. This commit tries to improve that.
* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
tt_cmap12_char_map_binary, tt_cmap13_next,
tt_cmap13_char_map_binary): Reject glyph indices larger than or
equal to the number of glyphs.
