Bug fix: GLX backend incompatibility with mesa & others
- Fix a bug that glx_bind_pixmap() doesn't work with mesa drivers. Thanks to Janhouse and mkraemer for reporting. (#7) - Use stencil buffer to attempt to eliminate potential double-paint issue in glx_render(). X Fixes doesn't guarantee the rectangles in a region do not overlap, and this may cause some regions to be painted twice, which would be a problem if we are painting transparent things. Now the target window must have a stencil buffer. Compiz uses its own region implementation to deal with this, but as a lightweight compositor we can't really do the same. It may have a positive or negative effort over performance. Callgrind result indicates basically no change in performance, but this may or may not be true. - Correctly distinguish GL extensions and GLX extensions. Sorry. :-D - Handle screen size. Thanks to tsmithe for reporting. (#7) - Rename OpenGL backend to GLX backend, because, we might have a EGL backend someday. - Add configuration file option `backend` to specify backend. Add `backend` to D-Bus `opts_get`. - Add OpenGL shader compilation code, but currently unused. - Minor adjustments. - Known issue: Window content doesn't get updated in VirtualBox, probably because its OpenGL implementation requires constant rebinding of texture. But that's really slow... - Known issue: Blur feature is still unimplemented in GLX backend.
