Problem with EGLImage

Hello!

I have artefacts when I use EGLImage on following configuration:

Distributive: Ubuntu 15.10

Mali user space driver: r7p0-02rel0

Weston commit: eaa43fc3103d67fe0182994032e851d10a2521a3

Wayland commit: d6d7dab487a8acd02c1fae45eea78954411c51b8

Wayland-protocol commit: 65d09ef404fb26cb513f4f836e904f415c425a8f

Board:  Odroid-xu4

For reproduce please apply attached (weston_simple_egl_mali_egl_image_test.dif) patch to weston, rebuild and run weston-simple-egl.

In this example:

* Init stage: We create texture and attach it to FBO, on next step we create EGLImage which is based on texture (created on previous step). EGLImage never used.

* Redraw stage: We clear texture(via FBO) with random color, on next step we draw texture to disaplay.

Without EGLImage all works fine. For disable usage of EGLImage please comment ENABLE_EGL_IMAGE define.

Thanks!
