Account for focus fading when enabling/disabling reverse video. Patch by Daniel Hahler.
24-bit direct color support (patch by Fengguang Wu)
Support directly setting RGB fg/bg colors via ISO-8613-3 24-bit
ANSI color escapes:
ESC[38;2;<r>;<g>;<b>m Select RGB foreground color
ESC[48;2;<r>;<g>;<b>m Select RGB background color
The killer applications for me are vim in tmux. It'll not only modernize
their look and feeling, but also bring more eye friendly color schemes.
Very helpful for long time programmers.
To avoid memory overheads and keep the patch non-intrusive, it takes the
approach to adapt the nearest color in an hidden 6x6x4 (88-color mode)
or 7x7x5 (256-color mode) color cube to the new 24-bit RGB color.
The pros/cons are:
+) least memory footprint (close to 0)
comparing to konsole, gnome-terminal etc. real 24-bit arrays
+) exact colors and excellent user feelings
comparing to xterm, mlterm, etc. approximating to 256 palette
+) usable in both the existing 88/256-color modes
Most vim GUI color schemes show up the same as gvim in rxvt-unicode's
88-color mode, not to mention the 256-color mode. Typical applications
only use one or two dozens of colors at the same time.
-) may not be able to show 2+ close 24-bit colors
RGB colors close to each other will likely fall into the same slot in
the 6x6x4 or 7x7x5 color cube. If necessary, it could be improved
effectively by implementing some collision avoidance logic, trying to
find empty/eldest slot in the +1/-1 r/g/b indices (ie. 3-8 neighbors).
The CPU overheads of map_rgb24_color() look ignorable: I feel no
perceptible slow down when doing vim operations in 24-bit color mode.

Fix crash when the number of columns is 1 and a 0 width character is inserted. In scr_add_lines, in the case when a 0 width character must be inserted in the first column of the current row, the calculation of the previous character (i.e., the last character of the previous row) is bogus. In particular, if the number of columns is 1, the 'tp' pointer points to either the first or third byte (depending on the size of text_t) of the rendition of the previous character, which is therefore corrupted by the assignment '*tp = n'. This triggers a crash if the font id in the rendition gets changed to the id of a font which is not loaded. Bug reported by Kuang-che Wu.
Change the width of underline and i-beam cursor to 2 pixels, based on a patch by Omar Sandoval.

need to check for both win and state
fix wrong check for scrollbar being active
Remove optimization in refresh for cells containing a space. The recent change introduced a regression and, while it can be fixed, it is not worth the risk.
Fix optimization in refresh for cells containing a space. scr_refresh skips refresh for cells containing a space and whose rendition attributes defining the bg color have not changed. However, the computation of such attributes erroneously assumes that, if reverse video is set, the bg color is given by the fg color, which is not true in the case where bg == fg. This causes cells with a space and bg == fg not being refreshed also when the reverse video attribute has changed, as observed in red hat bug #830236. Fix the bug by amending the attributes test so that the refresh of such a cell is performed if the reverse video attribute has changed.
Add DECSCUSR xterm extension to set the cursor to a vertical bar.

Simplify and correct lerp expression.
Fix regression in 2013-02-16 change. Do not include a leading partial wide char in the selection, as otherwise a leading tab is erroneously included in the case of a double-click word selection if pastableTabs is enabled.
Revert 2013-03-30 change.
Fix bug in core double-click word selection. selection_delimit_word does not account for (left) delimiters with width > 1. In such a case, it sets the starting position of the selection to the second column of the delimiter (thereby including the delimiter in the selection) rather than to the first column of the character next to it. This bug was masked before by 'selection_make' but a recent fix to the selection code revealed it.
Simplify.

Cleanup the code to save the current cursor coordinates when needed.
Honour cursorColor also when the cursor style is underline.
Simplify. ccol1 already accounts for Color_cursor if it is set.

When rendering the cursor, modify also the rendition of the filler chars that belong to the char in the cursor cell. This fixes a rendering bug that occurs if the character in the cursor cell has width > 1 and both it and the character to the right have the careful bit set and the same rendition. Bug reported by Tiago Resende.

fix for secondary screen
Fix bug introduced in 2012-05-28 change. If no scrollback exists and the terminal is resized, the lengths of the lines copied from the old screen buffer the new one are not properly initialized, causing artifacts on scrolling if saveLines is 0 (due to an optimization in scr_scroll_text). Bug reported by Bert Münnich.

Remove useless selection checks in scr_erase_screen. The check below the switch already clears the selection if it overlaps with the screen area to be erased.
