A bug was found where grid items were being drawn outside of the grid if
the item had a large span and the grid was defined as having gaps
between the rows/columns.
This was caused by an erroneous calculation of the
{row,column}_{start,span} properties.
ObjectType is now passed as an enum instead of a plain number. The
underlying type for both ObjectType and VirGLCommand have been reduced
to u8 to make sure they fit in the encoded command. Command length is
verified to not overflow u16.
Size and format information are the same for every implementation and do
not need to be virtual. This removes the need to reimplement them for
each driver.
Currently, the generated IPC decoders will default-construct the type to
be decoded, then pass that value by reference to the concrete decoder.
This, of course, requires that the type is default-constructible. This
was an issue for decoding Variants, which had to require the first type
in the Variant list is Empty, to ensure it is default constructible.
Further, this made it possible for values to become uninitialized in
user-defined decoders.
This patch makes the decoder interface such that the concrete decoders
themselves contruct the decoded type upon return from the decoder. To do
so, the default decoders in IPC::Decoder had to be moved to the IPC
namespace scope, as these decoders are now specializations instead of
overloaded methods (C++ requires specializations to be in a namespace
scope).
Both widgets now make use of their base class's scrolling timer and
now always accept drag selection updates on mousemove_event().
This guarantees much snappier feeling selections when actively moving
the mouse.
Renames on_automatic_scrolling_timer_fired() =>
automatic_scrolling_timer_did_fire()
The 'on_' prefix is usually reserved for AK::Function hooks.
Renames set_automatic_scrolling_{active,timer}() =>
set_automatic_scrolling_timer_active()

Previously, automatic cursor tracking widgets consumed all mouse
events but did not update their own hover state while active, meaning
Enter and Leave events were not being dispatched.
Fixes TextEditor's automatic selection scroll timer failing to stop
and start while autotracking. Its manual workaround in mousedown
is no longer needed.
