Needed so the value won't be left overwritten, Without this the wmPaintCursor can't use the pixel size & view matrices for drawing.

◆ ED_view3d_draw_offscreen_check_nested()

bool ED_view3d_draw_offscreen_check_nested ( )

Drawing off-screen is not supported while drawing, this is a simple check to use when the code path may occur within a draw call (Python scripting for example).

Utility func for ED_view3d_draw_offscreen

Parameters

ofs	Optional off-screen buffer, can be NULL. (avoids re-creating when doing multiple GL renders).
viewport	Optional viewport data, can be NULL. (avoids re-creating when doing multiple GL renders, allows keeping track of state across frames).
