Subject: Bug 1465 - Graph / GraphUI: Render a Region's ColorTexture in proper
aspect-ratio, letter-boxed or zoomed (config) + Bug 1466 Fix color mixing
Bug 1465: Region currently simply bloats a given texture to its region AABBox,
which renders textures with the wrong aspect ratio.
Add facility to program the texture-coordinates to either letter-box
or scaled-up (and cut) true aspect-ratio.
Default shall be zoom (scale-up and cut),
but user shall be able to set a flag in the Region for letter-box.
Have the shader clip texture coordinates properly,
best w/o branching to soothe performance.
See functions.glsl

Bug 1466: Current color mix: texture * color_channel * color_static
is useless in GraphUI.
color_static shall modulate the texture, which works.
But in case of color_channel (attribute/varying)
we want it to be mixed so it can become the more dominant color
for e.g. a border.
Desired is:
color = vec4( mix( tex.rgb * gcu_ColorStatic.rgb, gcv_Color.rgb, gcv_Color.a ),
mix( tex.a * gcu_ColorStatic.a, 1, gcv_Color.a) );
