# IDS common. A common is necessary since there is no graphics descriptor
# in the argument list of the kernel procedures. The data structures
# are designed along the lines of FIO: a small common is used to hold the time
# critical data elements, and an auxiliary dynamically allocated descriptor is
# used for everything else.
pointer i_kt # kernel image display descriptor
pointer i_tty # graphcap descriptor
int i_in, i_out # input file, output file
int i_xres, i_yres # desired device resolution
long i_frsize # frame size in chars
short i_maxframes, i_maxgraph # max num. of image frames, gr. planes
int i_linemask # current linemask
int i_linewidth # current line width
int i_linecolor # current line color
short i_pt_x, i_pt_y # current plot point, device coords
int i_csize # text character size
int i_font # text font
bool i_snap # true if a snap in progress
bool i_image # frame/bitplane data is for image
char i_device[SZ_IDEVICE] # force output to named device
