Proxy mode using GL_EXT_blend_color

I was thinking that {1,4} was a separate test = Test to see if OpenGL 1.4 is present. PC with a OpenGL 1.4 card would get "true".(Maybe the "is_ext" function does not work this way??? If I change {1,4} to {5,4} or any other set of numbers and include GL_E...

Micheus,Yes your version of the code is much better. The difference between a coder and a hacker.... Why are you thinking it needs to be like this? ({1,4}, ['GL_ARB_imaging', 'GL_EXT_blend_color']).Are you thinking that GL_EXT_blend_color is part of GL...

I forgot to respond to your information line text. I like it but maybe adjust it to read " Opacity Settings will work like a switch because your version of OpenGL doesn't support GL_ARB_imaging."oortEdit:I was thinking that ({1,4}, 'GL_ARB_imaging') requi...

You are probably right. Test for GL_ARB_imaging ... if that fails test for OpenGL 1.4... if that fails use the method that hopefully works for all other cards with the Moving/Stationary Opacity missing. Maybe have the info about this in the information li...

Micheus,I think you are right. Is it possible to change the else statement so that it tests for OpenGL 1.4 instead of GL_ARB_imaging (Current code) and GL_EXT_blend_color (Current fix for you). That way anyone with a card that supports the minimum of Open...

I found out that it was the "gl:blendColor(0, 0, 0, Opacity)" in the code that was causing the Shift Tab > Tab crashes. If blendFunc is part of the core it looks like blendColor is not. That part doesn't seem to work without ARB_imaging. I copied some ...
