Summary:
* Fix bold lines (BUG 402415).
* Make drawing pixel-perfect.
* Make line width proportional to font size.
* Move relevant code to separate file and namespace.
* Remove code for checking supported line characters from Character
class. Information about what is supported is now in one place
together width drawing code.
* Remove fontembedder/LineFont files (no longer used).
* Add test script for displaying supported characters table.
* Add triple and quadruple dashes (U+2504...U+250B).
* Change shade block characters (U+2591...U+2593) look. When
antialiasing is turned on, shades are drawn as transculent solid
rectangles with 25%, 50% and 75% alpha. This matches the characters
name/description and their usage. Without antialiasing, previous
method with patterns is used.

BUG: 402415
Test Plan:
== Common steps for all tests ==
* Open //Edit Current Profile → Appearance//.
* Turn on //Draw intense colors in bold font//.
* Turn off //Use line characters contained in font//.
* (Optional) select a font which is able to display bold characters in
Konsole (e.g. DejaVu Sans Mono).
== Check characters validity ==
* Run `./tests/line_block_characters_table.py`.
* Open //Edit Current Profile → Appearance//.
* By switching //Use line characters contained in font// on and off,
compare built-in characters drawing with characters from a font.
General shape and line directions must be the same. Small offsets,
line width differences (as long as proportions between lines in
a character are kept), and quality differences are allowed.
== Review overall quality ==
* Run `./tests/line_block_characters_table.py`.
* Review glyphs quality in different font sizes.
* Open //Edit Current Profile → Appearance//.
* Toggle //Smooth fonts//, review quality again.
== Check alignment ==
* Display `tests/UTF-8-demo.txt`
* At the bottom of the file you can find a few alignment images. Check
if all lines align properly. If you're unsure how it should look,
compare it with font characters by turning on //Use line characters
contained in font// option.

Summary:
There is a bug in the Qt glib event loop leading to timers never being
able to deliver signals.
Work around this by disabling the glib event loop.

Test plan:
From the referenced bug:
Stefan Westerfeld 2010-03-10 11:40:24 UTC
Running the following program within konsole:
#include <stdio.h>
int
main()
{
for (int i = 0; i < 100000000; i++)
{
fprintf (stderr, "foo %d\n", i);
}
}
leads to a freeze - not single message is printed - no reaction on
return. Only after a long time (30 seconds) something happens.
If I run the same program in an xterm, the messages are scrolling
through, as I would expect from that kind of output.

BUG: 230184
This seems to be the limit in all the test files I've been trying.
Without this we get an issue with too many combining characters where
Konsole will eventually just hang.
