NAME

       tickit_renderbuffer_save,  tickit_renderbuffer_restore,  tickit_renderbuffer_savepen  -  save and restore
       auxiliary state

SYNOPSIS

       #include <tickit.h>

       void tickit_renderbuffer_save(TickitRenderBuffer *rb);
       void tickit_renderbuffer_restore(TickitRenderBuffer *rb);
       void tickit_renderbuffer_savepen(TickitRenderBuffer *rb);

       Link with -ltickit.

DESCRIPTION

       tickit_renderbuffer_save() pushes a new entry to the buffer's saved state stack. This  will  capture  the
       current values of the auxiliary state, which can be later restored using tickit_renderbuffer_restore().

       tickit_renderbuffer_restore()  pops  the  most recent entry on the buffer's saved state stack and reverts
       the values of the auxiliary state back to the saved values.

       tickit_renderbuffer_savepen() pushes a new entry to the stack containing just the current pen value. When
       it is restored, it will only restore the pen; the other attributes will be unaffected.

AUXILIARY STATE

       The state saved and restored by these functions is:

       *      the virtual cursor position

       *      the translation offset

       *      the clipping rectangle

       *      the current pen

       *      the set of masked regions

       The pending content is not part of the state stack. It is intended that the state stack be used  to  help
       implement  recursive  drawing operations within the application, by dividing it into separate independent
       areas; allowing the state to be saved and restored between component parts.

RETURN VALUE

       None of these functions return a value.
