Adding support for OpenGL functions

[kc7bfi]

I have added code to expose some of the OpenGL functions. This was motivated by a need to determine the number of nVidia adapters present on a system. I had to make some changes to WinGDI.java and GDI32.java. I'm not sure why the pull request is attempting to replace the entire file, it may be due to indentation issues. Hope this is not a problem. I also removed a debug statmenet in the WinRas which was previously submitted.

Yes, the PR changes are all about tabs vs. spaces, check what the JNA code is and change your editor to those. It would be helpful, otherwise it's really hard to see history. I think it's a 2 spaces tab, but I could be wrong.

Please update CHANGELOG.

Is there a better exception we can catch here so that the test is properly ignored when you don't have an NVidia card?

[kc7bfi]

The exception is only if something goes wrong. If the nVidia extensions are not supported then 0 is returned.

So this is just to get the stacktrace? I think the test should expect that
function to return >= 0 and not catch any errors.

OK, I'll make the change. David

[kc7bfi]

I committed and pushed the change. Do I need to do anything with the pull request?

[dblock]

Code looks good otherwise, I'll merge after your changes.

I'm going to refork and retry the changes. It appears that my Eclipse was modifying the indentation/etc and I cannot seem to get back to where everything is as it was. Is there an easy way to restore my repository to the master without deleting and creating a new fork?

Backup the local git repo so you don't lose changes.

Then bring master back to be in sync with upstream JNA.

git remote add upstream git@github.com:twall/jna.git

git checkout master
git checkout -b opengl-try1 # new branch
git push origin opengl-try1 # push to github
git checkout master
git reset --hard HEAD~100 # reset 100 commits back
git pull upstream master # sync with master
git push origin master -f

Now you have a clean master and a opengl-try1 branch with your changes, next time create a new branch before committing anything with git checkout -b opengl-try2 for example.
