A "Tray" is a sunken container area for widgets. The first intended
client of this style is the GUI::FilePicker's common locations frame.
Thanks to @nvella for coming up with the term "Tray" :^)
Menu items can now also have Alt shortcut, and they work the same way
top-level menu Alt shortcuts do. This replaces the previous "type to
search" mechanism we had in menus.
Double kfree() is exceedingly rare in our kernel since we use automatic
memory management and smart pointers for almost all code. However, it
doesn't hurt to do some basic checking that might one day catch bugs.
This patch makes us VERIFY that we don't already consider the first
chunk of a kmalloc() allocation free when kfree()'ing it.
Creating a file while having a file or directory selected will now
create the file under the selected directory, or in same directory as
a selected file.
Creating directories works the same way.
Right click -> Open on selected files will now open the selected files.
Deleting selected files will now delete the selected files.
As suggested by sagefarrenholz this was accomplished by adding a private
function HackStudioWidget::selected_file_paths() that returns a
Vector<String> of the current project tree selection.
Function HackStudioWidget::selected_file_names() is removed due to not being used.
I dont know why we do a fast path in the Kernel, but not in Userspace
Also simplified the byte explosion in memset to "explode_byte"
it even seemed so, that we missed the highest byte when memseting something
The first one is for disabling the PS2 controller, the other one is for
disabling physical storage enumeration.
We can't be sure any machine will work with our implementation,
therefore this will help us to test more machines.
This is a pretty naive implementation that works well. The precision
parameter is interpreted as "maximum precision" instead of "minimum
precision", which in my opinion is the most useful interpretation.
As per the PNG specification: "Filter method is a single-byte
integer that indicates the preprocessing method applied to the
image data before compression. At present, only filter method 0
(adaptive filtering with five basic filter types) is defined."
As per the PNG specification: "For all x < 0, assume Raw(x) = 0 and
Prior(x) = 0. On the first scanline of an image (or of a pass of an
interlaced image), assume Prior(x) = 0 for all x."
