egl: call _eglError within _eglParseImageAttribList
As per EGL_KHR_image_base: If an attribute specified in <attrib_list> is not one of the attributes listed in Table bbb, the error EGL_BAD_PARAMETER is generated. We should set the error as opposed to simply log it. Currently we have a partial solution, whereby only some of the callers call _eglError(). Since that has proven to be less robust, simply set the error by the function itself and change the return type to EGLBoolean, updating the callers. So now the code is slightly simpler. Plus the follow-up fixes will be easier to manage. Signed-off-by: Emil Velikov <[email protected]> Reviewed-by: Eric Engestrom <[email protected]>
