The common codebase in mesa does that already, so we don't need to figure that out. Oh, I did not know that. I've found only that types of glViewport parameters are GLint and GLsizei. In /usr/include/GL/gl.h they are declared as: typedef int GLint; /* 4-byte signed */ typedef int GLsizei;/* 4-byte signed */ so I thought that negative values are possible. Next time I will read more carefully OpenGL specification ;) Btw, you should really give me your sf.net id so that I can add you to the project.
