The call was an unimplemented stub. It now writes syllable state 0 and
returns OK for every character outside the Thai block, where a PS4
firmware 11.00 libSceFont measures 1, 3 or 4; Thai characters throw as
not implemented. A null character or result returns
SCE_FONT_ERROR_INVALID_PARAMETER, and a null character writes 0 to a
non-null result, as measured. The signature follows SharpProspero.

The second argument is an out pointer to the writing's letter step, as
KytyPS5 and the SharpProspero bindings declare it. It was filled as a
letter step struct, which wrote 64 bytes over the caller's 8-byte
pointer. The letter step now lives in the writing and the call stores
its address, or null when there is no current step.

sceFontSetScriptLanguage, sceFontGetScriptLanguage,
sceFontSetTypographicDesign and sceFontGetTypographicDesign threw. With
the signatures SharpProspero declares, a font handle now keeps the
language set for each script and the feature set for each typographic
design, under the handle's lock, and returns them, with 0 for one never
set. They do not change shaping or rendering yet; TechnicalDebt records
the assumptions.

Detach the device cache buffer attached by sceFontAttachDeviceCacheBuffer. The signature is taken from the IDA type database of Orbital: it takes the library, a pointer to receive the buffer and a pointer to receive its size. When no cache buffer is attached, it reports NOT_ATTACHED_CACHE_BUFFER. If the library allocated the buffer itself and no buffer pointer is passed, the memory is freed. The owned bit is cleared and device_cache_buf is reset to null.
PPSA01325 stops on sceFontGlyphDefineAttribute right after generating a character glyph: it sets attribute 0x11 to 0 on that glyph, deletes it without using it, and draws the character with sceFontRenderCharGlyphImageHorizontal. The meaning of the attributes is unknown, so the call checks the glyph and ignores the rest; TechnicalDebt lists it under silent stubs.

Report the face's glyph count and the glyph index of a character through
the library's driver; the FreeType driver gains its glyphs_count entry.

Return the kerning between two character codes at the render scale of
the font, the one set by sceFontSetupRenderScalePixel and
sceFontSetupRenderScalePoint, and fail with NOT_BOUND_RENDERER when no
renderer is bound. sceFontGetKerning keeps its behaviour and shares the
FreeType lookup.

Report the horizontal and vertical resolution kept in the font handle's
style block, as set when the font is opened (72 dpi) or by
sceFontSetResolutionDpi. Error handling follows the other handle getters:
an invalid handle or two null outputs fail and clear the outputs.

Ported from shadPS4 (GPL-2.0-or-later) with system fonts removed, stubs made to throw,
and sceFontCloseFont implemented.
