Subject: gl-renderer: Force call to glUseProgram() when activating debug binding
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03fb4ef41e0a2feec44a9362d42bbfa9d5be3464;p=profile%2Fivi%2Fweston-ivi-shell.git

gl-renderer: Force call to glUseProgram() when activating debug binding

When redrawing surfaces, use_shader() checks if the desired shader is
already in use to avoid a call to glUseProgram(). However, once the
debug binding is activated, that same check would prevent the usage of
the recompiled shaders until something cause a different shader to be
passed to use_shader().
