So I fixed the damn transparency issues in Mono.

Before: Ugly white BG. http://i.imgur.com/ay6XE.png
After: Works awesome as on Windows. http://i.imgur.com/YXjNQ.png

Basically it was some bugs in libgdiplus... My fixes are kind of a hack. Maybe they break other things but NSMBe works well now.

Installation instructions
Find the existing libgdiplus.so (or libgdiplus.so.something) in your system and replace it with the one in the zip file.
On debian-based Linux it's on /usr/lib.

It's a good idea to take a backup of the original one, just in case.

You can also get it from my Github and build it from source.

Okay, two things:
1. If this fix works on Mono for Linux, what about Mono for Windows?
2. If you're SURE this will break things somewhere else, how about you go find what it breaks. Because following this track of laziness just hacking this and that will eventually turn it into a pile of hacks. So how about you write good code that fixes it?

Mono on Windows: I think it uses the native GDI+ so this problem isn't present.

About the fix: It fixes NSMBe. Given how hacky is winforms/libgdiplus on Mono, everything that I change will break something else. My intention is to make NSMBe work. Not to get my fix accepted upstream (because it won't, there's been no development on libgdiplus since 6 months).

So I fixed NSMBe in Mono, that's all.

Compiled for x86_64 processors. Since 64-bit mono cannot use 32-bit library, I had to compile it.

Use it if you have 64-bit Linux.

Thanks! Edited first post
