When compiling Julius with Gtk+ support for visualization, it needs some structures from libjulius that are conditionally compiled based on VISUALIZE define. To try and define it at compile time, Julius uses --enable-visualize flag. Libjulius, however, doesn't use that flag and ends up not defining this variable, which causes compilation errors with --enable-visualize. Fix that by adding a configure flag for --enable-visualize.
GTK is now called Gtk+, and it works on Wayland as well.
Just like libjulius received an --enable-visualize flag, this commit readds Gtk+ support in Julius by properly checking for Gtk+ with pkg-config. Warning: this commit makes Julius unbuildable. The build issue will be fixed in the next commit.
After properly reintroducing the --enable-visualize flag to configure, this commit updates the code of visual.c to work on Gtk+ >= 3.16. This rework involved the following things: - Drop GdkGC usage and use GtkStyleContext instead - Drop GdkPixbuf and use cairo_t - Use CSS styles rather than GdkColors - Adapt some other minor things to work with new Gtk+ internals - Add a headerbar to the window
By moving the bottom texts to labels, we're able to simplify the drawing code a little bit and completely get rid of the draw_background() function.
Instead of using a set of pre-defined zoom levels that are not based on the visible area of the window, the zooming action was very confusing and had some weird behaviors, e.g. when zooming 8x and the tree actually shrinks. Fix this misbehavior by adding a set of buttons at the headerbar and using relative zooming rather than absolute zooming.
Using CALLBACK_EVENT_SEGMENT_END doesn't give us a valid backtrellis pointer and causes segmentation faults when searching.
To make it more visually appealing, do the following changes: - Improve the side widgets to be more like a list. - Move the search bar to the header. - Reorganize side widgets.
For the sake of sanity, the drawing code omits some words from being rendered, otherwise it'd be too hard to understand the backtrellis. The problem with that approach is that we don't know where some branchs point to, since some words are not rendered. Fix that by showing a sidebar with the words, in the order they're displayed in the graph.
The view area is the most important piece of graph here, thus we should make it the most visually recognizable section of the window.
To improve the rendering and ease the visualization of the word trellis, this patch adds the following changes: - Render small dots at the end of each line - Show horizontal stripes, so we can easily detect which word each line is related to.
Instead of always showing the GUI when compiling with visualization support, add a new flag '-visualize' so we can still run Julius like before (without an actual user interface).

This is an attempt to port the word trellis visualizer to Gtk+ 3. Comments are more than welcomed.
