Major changes are:
The layout and mouse handling has been rewritten to always center
images in the window.
QuickShow now accepts multiple images on drag and drop. The first
image gets opened in the current window, further images are opened in
new processes.
QSWidget now loads images on its own with QSWidget::load_from_file().
An on_drop callback has been introduced for QSWidget.
Added an open menu.
Added an about box and placeholder icons to the application.
QuickShow now starts without loading the sunset-retro wallpaper.
QSWidget::relayout get triggered before setting a bitmap to display
while setting the widget as the main widget of the window.
I've added a null check to the paint event too to make sure the
widget works with no bitmap set.
I started adding things to a Draw namespace, but it somehow felt really
wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename
the library to LibGfx. :^)
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
We now try to open image files dropped on us from FileManager. :^)
The QuickShow code is not exactly well-factored, and should be fixes up
to not do the same thing twice, etc.
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.
This avoids building the code twice, and will encourage better separation
of concerns. :^)
This needs more work and polish, but it's a step in a more pleasant and
useful direction.
Also turn QuickShow into a fully-fledged "application". (By that, I really
just mean giving it its own Applications/ subdirectory.)
