Summary0028098: Visualization - errors in tests when using OpenGL ES (ANGLE)
DescriptionWhen building OCCT in GLES mode (HAVE_GLES2=true) using ANGLE libraries, about 80 tests fail. Here is a list of different problems observed:

1. Export to vector formats (PDF, SVG etc.) GL2PS does not work (as expected?)

2. Command vboundings does not draw a box [0029823 should fix the issue]
