/* Modal Operator Geometry Preview
|
|
*
|
|
* Several modal operators (Fill, Interpolate, Primitive)
|
|
* need to run some drawing code to display previews, or
|
|
* to perform screen-space/image-based analysis routines.
|
|
* The following structs + function prototypes are used
|
|
* by these operators so that the operator code
|
|
* (in gpencil_<opname>.c) can communicate with the drawing
|
|
* code (in drawgpencil.c).
|
|
*
|
|
* NOTE: All this is within the gpencil module, so nothing needs
|
|
* to be exported to other modules.
