* Generates QR codes using the qrencode library functions and prints them
using terminal escape sequences and the special "block" characters.
* Supplies a static QR buffer that can be used to accumulate output for
later conversion into QR codes.
* Adds qrencode debugger command that allows to generate QR codes for
arbitrary strings.
* Adds qrappend, qrflush and qrclear to manipulate the QR buffer.
qrappend can be the target of a pipe to accumulate output from other
commands. qrflush causes the QR buffer to be encoded and cleared and
qrclear only clears the QR buffer.
* Adds qrconfig that allows changing the QR code version, determining
what size QR codes are to be used.
Characters 17, 18 and 19 (device control 1, 2 and 3) become "full block",
"upper filled block" and "lower filled block". Using back- and foreground
color inversion these could be reduced to a single "half block", but
having them available as idividual chars is more convenient.
The kernel strdup will still be used, as the local symbol doesn't
override that. Since we must not use strdup from within the kernel
debugger (as it does malloc from the normal heap), force the use of
the internal strdup that gets redirected to debug_malloc.
* Remove several hard-coded colors
* Reduce slightly the font size in the file info panel (#6909).
* Don't hardcode the font height, compute it
* Fix a bug where deploying the bottom panel makes the current
window width the new minimum width
* Don't hardcode the bottom panel's height, compute it
(allows better font size tolerance).
Introduce a function to generate the string representation of a bitrate
(kbps, mbps, gbps, etc..)
* Factor out the code from MediaPlayer InfoWindow
* Allow different bases (/1000 or /1024)
Based on printf debugging the correct left value is actually -1, not 0, but
instead of hard-coding numbers it makes more sense to use the existing value.
I'm not sure if a -1 left value makes much sense, but overall this seems to
work and does not have the scrolling artifacts.
But overall I think ShowImage needs more layout management. Doing all this
moving and resizing manually is error prone.
Fixes#8648.
* Extract the scrollbar change based on the mouse wheel delta into a protected
method of BView.
* Call that method from BScrollBar's MessageReceived.
With this change it is now a bit easier to scroll horizontally around the
system by putting the mouse cursor over a horizontal scrollbar and using the
wheel.
Fixes#8631.
After coming back from fullscreen mode, horizontally scrolling a zoomed
image would draw vertical lines from the right border. Seems like an
off-by-one issue. This fixes it in my tests... hope it's properly done.
If you've zoomed in fullscreen mode and moved the mouse to the top of the
screen, the toolbar didn't appear. You had to scroll up to the top of zoomed
image first. Using the screen coords instead of the view coords fixes this.
As the downloadable files are now hosted on haiku-files.org and the user is
presented the Intel license at the beginning of the script, the function
OpenIntelFirmwareWebpage is unneeded.
