* gmc-chargrid.c: Changed the struct attr with pointers mess with
something saner.
Added an in_resize flag to avoid calling our internal signal
handlers recursively.
(gmc_char_grid_draw): Added proper draw handler for our case; the
widget's window does not fill its allocation.
(paint): New wrapper for update_region(); it converts window
coordinates to row/column character coordinates.
(gmc_char_grid_expose): Use paint().
* gmc-chargrid.c (gmc_char_grid_get_size): New public function.
(gmc_char_grid_put_text): New public function. It is the same as
gmc_char_grid_put_str, but can take any arbitrary string plus its
length.
(gmc_char_grid_put_char, gmc_char_grid_put_str,
gmc_char_grid_put_text): These functions now take a background
pixel parameter --- the GmcCharGrid widget now supports fg/bg attributes.
* gmc-chargrid.h: Changed colors field to attrs.
* gmc-chargrid.h:
* gmc-chargrid.c: New Character Grid widget for the file viewer.
This is a very lean and fast widget for displaying a grid of
monospaced characters. Just like a crippled-down terminal.
