grid: implement a memmove-sort-of function
grid_memmove() moves cell data from one index to another, taking the
grid offset into account.

wip: use a sliding window instead of memmove() to scroll
Instead of memmoving a large amount of data on every scroll, use a
sliding window. That is, each time we scroll, we offset origin.

colors: store as doubles, rather than uint32_t
Since cairo uses doubles, we don't want to have to convert a uin32_t
to double values every time we render a cell.

grid: attributes now track whether we've set a foreground/background color
This means we don't have to explicitly set the foreground/background
to the grid's default colors whenever we reset/clear a cell, and we
can instead simply memset() the entire cell to 0.

This also means the renderer has to get the default color when
rendering a cell without a foreground/background color set.

scroll: let the render erase the scrolled up region
The grid scroll operation no longer inserts a DAMAGE_ERASE operation,
but instead manually clears the region. The render does the
corresponding thing.

scroll-region: don't clear damage queue when changing scroll region
Vim, for example, changes the scroll region every time you scroll a
single line. Thus, resetting the damage queue is slow.

This reworks the damage handling of scroll updates:

* Split damage queue into two: one for scroll operations and one for
  update/erase operations.
* Don't separate update/erase operations inside/outside the scroll
  region
* Store the current scroll region in the scroll damage operation. This
  allows us to stack multiple scroll operations with different scroll
  regions.
* When updating update/erase operations after a scroll operation,
  split the update/erase operations if necessary (the current scroll
  operation may have a scroll region different from before, thus
  forcing us to split existing update/erase operations.
* The renderer no longer erases after a scroll. The scroll operation
  also adds an erase operation. This also means that erase operation
  are subject to adjustments by later scroll operations.

csi: add function param_get()
Returns the value of parameter #idx, if available, or the specified
default value.

If the specified parameter does exist, but is 0, the default value is
returned.

vt: wip: implement scrolling region
This is largely untested, but existing scrolling code has been
converted to using a terminal-global scrolling region that is defined
as start-end of the scrollable region.

This is compared to the old code where the scrolling region where
defined in terms of marginals, counted in lines from top and from
bottom.

This currently duplicates the code paths for DAMAGE_SCROLL; there are
many similarities between the two, but also major differences...

resize: bug: we're not in alt screen mode at startup
When we start up, the cells pointer, *and* the alt screen pointer are
both NULL. Hence we incorrectly decided we were initially in alt
screen mode.
