* Sync OpenBSD patchset 226:Tiago Cunha2009-08-09
| | | | | | | | | | | | | | Change the way the grid is stored, previously it was: - a two-dimensional array of cells; - a two-dimensional array of utf8 data; - an array of line lengths. Now it is a single array of a new struct grid_line each of which represents a line and contains the length and an array of cells and an array of utf8 data. This will make it easier to add additional per-line members, such as flags.

* When resizing a screen smaller in alternate screen mode, all the lines neededNicholas Marriott2009-07-18
| | | | | | | could be consumed by deleting from the bottom, leaving none to be removed from the top. In this case, don't call grid_view_delete_lines with ny of 0 as this is incorrect and causes a bounds check to fatal error if built with -DDEBUG.

* Better UTF-8 support, including combined characters. Unicode data is now storedNicholas Marriott2009-03-28
| | | | | | | | | | | as UTF-8 in a separate array, the code does a lookup into this every time it gets to a UTF-8 cell. Zero width characters are just appended onto the UTF-8 data for the previous cell. This also means that almost no bytes extra are wasted non-Unicode data (yay). Still some oddities, such as copy mode skips over wide characters in a strange way, and the code could do with some tidying.
* Step 2 of the Grand Plan To Make UTF-8 Better.Nicholas Marriott2009-03-28
| | | | | | | | | | | | | | | | | | | Split grid into two arrays, one containing grid attributes/flags/colours (keeps the name grid_cell for now) and a separate with the character data (called text). The text is stored as a u_short but is treated as a uint64_t elsewhere; eventually the grid will have two arrays. I'm not happy with the naming so that might change. Still need to decide where to go from here. I'm not sure whether to combine the peek/set functions together, and also whether to continue to treat the text as a uint64_t (and convert to/from Unicode) or make it a char array (of size one when UTF-8 disabled, eight when enabled) and keep everything as UTF-8. Also since UTF-8 will eventually become an attribute of the grid itself it might be nice to move all the padding crap into grid.c.
