This ensures that the gradient does not paint over the rulers at
any zoom level, and also shows the guidelines/handles even when the
gradient is clipped.
The main change here is to implement and use the "container for element"
algorithm. But also, adjust the errors we return. Errors thrown by
`scroll_element_into_view()` are not related to the scrolling itself,
so should not claim to be. `UnsupportedOperation` is more accurate than
`InvalidArgument` when we're expressing that the operation isn't fully
implemented.
This probably won't be the final API for getting color spaces
from images, since some formats just store an "is sRGB?" flag
instead of a full profile. Instead, once everything works,
we probably want to give every Bitmap a pointer to some
color space abstraction.
But we can always change this later, once things are further along
and better understood.
After 5ac57f9, we could no longer run "serenity.sh run lagom TestString"
because the TestString binary now lives in a subdirectory under
Build/lagom. Thus the existing method of running "$BUILD_DIR/TestString"
could not work.
This adds a "run-lagom-target" custom target to Lagom, to run a command
and pass arguments to that invocation. It turns out there really isn't a
"pretty" way of doing this with CMake or Ninja. But we can pass these as
environment variables for CMake to interpret. We just must be careful to
massage arguments into a CMake list.
This will cause page faults to be generated. Since the previous commits
introduced the handling of page faults, we can now actually correctly
handle page faults.
The code in PageDirectory.cpp now keeps track of the registered page
directories, and actually sets the TTBR0_EL1 to the page table base of
the currently executing thread. When context switching, we now also
change the TTBR0_EL1 to the page table base of the thread that we
context switch into.
The handling of page tables is very architecture specific, so belongs
in the Arch directory. Some parts were already architecture-specific,
however this commit moves the rest of the PageDirectory class into the
Arch directory.
While we're here the aarch64/PageDirectory.{h,cpp} files are updated to
be aarch64 specific, by renaming some members and removing x86_64
specific code.
