Is there a way to increase glPush/PopMatrix() stack size ?

The standard minimal stack size is 32, but i wonder if there is a way to user-increase this size ? maybe using a specific gl or wgl extension ?

Thankyou in advance,
Alexander

i'll give the points only if the answer is yes, and explaining how to do it...
No answer will mean a "no", thank you...

you can use glGetIntegerv(GL_MAX_MODELVIEW_STACK_DEPTH, GLint *params) to find the stack size on your implementation

Sorry, my question isn't maybe clear enough : it concerns "how to increase the stack size", not "how to get current stack size".

It is often a hardware-constrained parameter, and not up for debate or adjustment.  

I believe OpenGL implementations are required to have a GL_MAX_MODELVIEW_STACK_DEPTH of at least 32.  That ought to be enough for anybody. :)  Seriously, if you need more than a few maybe you should reconsider how you use the modelview stack.

I think the question you should ask yourself is "Why do I need a matrix stack larger than everybody else?".

Hi, i know the answer to this question : the problem is that when using wglUseFontOutlines() to generate 3-D fonts and if I use polygon antialiasing on generated fonts, i'm able to do only 3 glPushMatrix() before calling generated font display lists. If i do more than 3 push, GL returns a stack overflow error. (of course, there is a "pop" for each "push" !!)
I've found a solution : when using FSAA (Full Scene Anti Aliasing) i've a better rendering effect and this problems dissapears.That's why i'm thinking that it is maybe a driver's or Window's bug...

Anyway, if there is a way to increase push/pop stack size (through some kind of GL extension) i'm still interested in it, it could be useful in other cases where i've no control on generated display lists, etc...
