octave: libinterp/corefcn/gl-render.cc annotate

annotate libinterp/corefcn/gl-render.cc @ 22369:17c9cc85842e

Fix display of scaled images in OpenGL toolkits (bug #48879). * gl-render.cc (draw_image): Adjust spacing and wrap long lines, for readability. * graphics.cc (convert_cdata_2): Use 'fix' rather than 'round' when scaling data to climits. * imagesc.m: Add %!demo to test display.
