Gerbv does not Acknowledge Rotation of Circle Primitives in Aperture Macros #254

This might also be connected to Issue #253 but I'm not entirely sure.
I have an aperture macro that creates a C-shaped aperture that can be rotated.

Here is how it looks in Kicad

and here is how it looks in Gerbv
Image

I looked at the code and I think the problem is in the gerb_image.c file at line 542.

                        case GERBV_APTYPE_MACRO_CIRCLE:

                            /* TODO: test circle macro center rotation */
                            sam->parameter[CIRCLE_CENTER_X] *= trans->scaleX;
                            sam->parameter[CIRCLE_CENTER_Y] *= trans->scaleY;
                            gerbv_rotate_coord(
                                sam->parameter + CIRCLE_CENTER_X, sam->parameter + CIRCLE_CENTER_Y, trans->rotation
                            );

                            if (trans->scaleX != trans->scaleY) {
                                err_scale_circle++;
                                break;
                            }
                            sam->parameter[CIRCLE_DIAMETER] *= trans->scaleX;
                            break;

I guess nobody got around to testing it.
Not only that, but when I compared it to "case GERBV_APTYPE_MACRO_LINE22" at Line 591, it looks like "case GERBV_APTYPE_MACRO_CIRCLE" is missing a lot of the features and contingencies that allow the rectangles to be rotated. That would explain why Gerbv is able to rotate my rectangles, but not my circles.

case GERBV_APTYPE_MACRO_LINE22:
                            /* Lower left line rectangle */

                            /* Using LINE21 parameters array
                             * indexes for LINE21 and LINE22, as
                             * they are equal */
                            if (trans->scaleX == trans->scaleY) {
                                sam->parameter[LINE21_WIDTH] *= trans->scaleX;
                                sam->parameter[LINE21_HEIGHT] *= trans->scaleX;

                            } else if (fabs(sam->parameter[LINE21_ROTATION]) == 0 || fabs(sam->parameter[LINE21_ROTATION]) == 180) {
                                sam->parameter[LINE21_WIDTH] *= trans->scaleX;
                                sam->parameter[LINE21_HEIGHT] *= trans->scaleY;

                            } else if (fabs(sam->parameter[LINE21_ROTATION]) == 90 || fabs(sam->parameter[LINE21_ROTATION]) == 270) {
                                double t;
                                t                             = sam->parameter[LINE21_WIDTH];
                                sam->parameter[LINE21_WIDTH]  = trans->scaleY * sam->parameter[LINE21_HEIGHT];
                                sam->parameter[LINE21_HEIGHT] = trans->scaleX * t;
                            } else {
                                /* TODO: make outline macro */
                                err_scale_line_macro++;
                                break;
                            }

                            sam->parameter[LINE21_CENTER_X] *= trans->scaleX;
                            sam->parameter[LINE21_CENTER_Y] *= trans->scaleY;

                            sam->parameter[LINE21_ROTATION] += RAD2DEG(trans->rotation);
                            gerbv_rotate_coord(
                                sam->parameter + LINE21_CENTER_X, sam->parameter + LINE21_CENTER_Y, trans->rotation
                            );
                            break;

There might be more code to fix that I'm missing, but I figured this was a good place to start.
