[BUG] Rendering arrows with different up_axis, color in OpenGLRenderer

[eric-heiden]

Bug Description

The up_axis argument is not respected when multiple arrows with different up_axis settings are rendererd in the OpenGLRenderer.
The color argument also appears to be broken when rendering multiple arrow instances.

Code for reproduction:

import warp as wp
import warp.render


renderer = wp.render.OpenGLRenderer(draw_axis=False)

pos = wp.vec3(0.0, 0.0, 0.0)
rot = wp.quat_rpy(0.3, -0.4, 0.5)

renderer.begin_frame(0.0)
for i in range(3):
    axis = wp.vec3(0.0, 0.0, 0.0)
    axis[i] = 1.0
    renderer.render_arrow(f"arrow_{i}", pos=pos, rot=rot, up_axis=i, color=axis, base_radius=0.05, base_height=1.0)
renderer.end_frame()

renderer.save()
