[compiz] grid plugin isn't drawn correctly

[Alexandros Frantzis]

When dragging a window to the edge of the screen, an orange rectangle should be drawn to indicate that the window will be tiled there. Using the latest packages from unity-3d-gles on the panda, the rectangle is not drawn correctly (only the upper triangle is drawn, see attached image).

FWIW, I am using the latest sgx drivers from omap-trunk

I ported the initial version of the grid plugin to GLES, here's the patch: http://bazaar.launchpad.net/~linaro-graphics-wg/unity-gles/compiz/view/head:/debian/patches/088_grid_work_with_gles.patch

Probably a bug while setting the vertex data.

Hi Ricardo,

streamingBuffer->begin () is using "GL_TRIANGLES" by default, so only one triangle is rendered when you specify four vertices. Please use "streamingBuffer->begin (GL_TRIANGLE_STRIP);" in your patch, which should be able to solve this problem.

Hey Jammy!

Yeah, just tested your suggestion and it indeed fixes the issue :-) I'm just uploading a new package.

Thanks man!
