[Bf-committers] Images in Panels..

[dimitris chloupis]

I did not say bgl is buggy , I only said that I am currently experiencing problems I can't isolate with some really weird behavior. My assumption is that is bugs with my code and not bgl. 

The problem I have right now is that the texture does not display the transparency correctly, and that my gui seems to leak on the buttons (menu buttons) of blender spaces/areas/windows . I am now in the process of cleaning up my code to make sure I am not doing anything stupid with bgl. 

If I find a bug with bgl rest assured I will report it to the bug tracker with an example case attached to it.  

All I am saying is that using bgl can be rather challenging. For example using image.gl_load() outside a draw function will crash blender, yet there is no such warning in the docs and it looks like a weird behavior image.gl_load() to be contained inside a draw . Doesn't it slow down blender. Attaching a image.gl_free() for example inside the same draw does slow down blender considerably. 

So all I am saying bgl can be quite tricky to use.

@dimitris - I dont think your explanation of `bgl` as buggy is really
correct, bgl just wraps OpenGL - there isnt much to it,
the issues you have are almost certainly issues dealing with sharing
an OpenGL context with blender - which will free images from OpenGL
memory to prevent running out of texture memory for unused textures in
scenes.
