Since the alpha blend configuration should not change between most calls
of draw_primitives it makes no sense to reinitialize the blend factors
for every rasterized triangle.
The alpha blend factors are now set up whenever the device config
changes. The blend factors are stored in struct AlphaBlendFactors.
This adds member functions Device::rasterize_triangle() and
Device::shade_fragments(). They were free standing functions/lambdas
previously which led to a lot of parameters being passed around.
This adds a counter to the debug overlay that displays the average
percentage of SIMD lane utilization.
This number represents the number of pixels that were output for each
quad. A utilization of 100% means that all 4 SIMD lanes were used and
no pixels were masked out before being written to the color buffer.
Now, each new filter only has to describe how to actually change
the bitmaps, and the common logic of pulling out the bitmap from the
layer, and marking the action as done, etc is all handled in the
`Filter` base class.
This also makes it possible to apply filters to external bitmaps,
which are not embedded in a `Layer` (which we can use to preview
filters in the future!)
This makes interrupting `sleep 10; echo hi` not print `hi` anymore,
which is the expected behaviour anyway.
Also fixes the problem with fast-running loops "eating" interrupts and
not quitting.
Running `./package.sh interactive` in a port directory will
spawn a new shell with the serenity build environment set up.
This makes porting software much easier as build commands can
be run interactively instead of having to modify package.sh
just to test things.
Add them in `<Kernel/API/Device.h>` and use these to provides
`{makedev,major,minor}` in `<sys/sysmacros.h>`. It aims to be more in
line with other Unix implementations and avoid code duplication in user
land.
The documentation tooltip and parameters hint tooltip initialization
functions are now fallible and now call try_set_main_widget
instead of set_main_widget. They are only called by Editor's new
custom try_create function.
build_process_window now uses try_set_main_widget and might return an
error. process_properties_action handles a possible error by simply
not updating the process window if an error occured while building it.
Briefly flash the menubar menu containing the keyboard shortcut action
to give the user immediate visual feedback on their interaction with the
system.
