Hello,
This is a small PR that factors out
Program::draw_*commonalities (setup/cleanup) into two new methods:draw_withanddraw_elements_with. These methods accept adrawcallback that is called between setup and cleanup, and are used to implement existingdraw_methods.Context: I need to implement some legacy
GL_LINESrendering and this is the smallest-yet-useful (hopefully!) set of changes I could come up with that allows me to do that. This means the two new methods must be public to be useful.Best regards,
