| |
| This primtive defines an array of markers. Their size is defined |
| in pixels and independent from the view transformation which makes |
| this primitive highly view-dependent. It is also transformation |
| invariant, so that the bitmap is always visualized unscaled and |
| unrotated. |
| It is used e.g. for grid position visualisation. The given Bitmap |
| (with transparence) is defined to be visible centered at each of the given |
| positions. |
| It decomposes to the needed number of BitmapPrimitive2D's, so it would |
| be efficient to handle it directly in a renderer. |
