Following the pointers that move with REMAINING OB lands on four identical
objects whose first word is 0x820B2A64. Read live: that address holds 32
consecutive code pointers in 0x823c43b0..0x823c45a0 terminated by 0xfffffffc - a
vtable - and sylpheed.db has three ref xrefs to it from sub_823C3060,
sub_823C3148 and sub_823C31E0, i.e. three construction sites, the same pattern
the splash item vtable shows. No name: the disc's RTTI carries none.
The instance is a textured quad: a pixel size at +0x1c/+0x20 (34 x 42 for a
digit) and four vertices at +0x30/+0x48/+0x60/+0x78, each a colour and a UV pair.
The four UVs measured are the corners of an axis-aligned rectangle in order, all
0xffffffff.
The atlas size is a check rather than a guess: the UV rectangle is 0.0265 x
0.0547, and multiplying by 1280 x 768 gives 33.9 x 42.0 against the 34.0 x 42.0
stored in the object's own size fields - two independent fields agreeing to a
rounding step.
Also recorded: these objects churn. Re-reading an old pointer target a minute
later returned unrelated data, so this is a snapshot of a live pool.
