model matrix as Signal is silently picky about element type

[goretkin]

This does not plot the square.

using GLVisualize, Reactive, GLWindow

window = glscreen()

o = HyperRectangle{2,Float32}([100.0,100.0],[-100.0,-100.0])
tx = Signal(eye(SMatrix{4,4,Float64})) # change to Float32 for it to work
vis = visualize(o, model=tx)

_view(vis, window, camera = :orthographic_pixel)

[SimonDanisch]

Ah yeaaah, sorry about that... I need to fix this somewhere ;) This used to work, until someone half way implemented Float64 support :D

[goretkin]

No worries! If you have an idea about what's going on (and time to explain!), I wouldn't mind knowing about it.

[SimonDanisch]

well, the shader has matrix type hardcoded as Mat4f0(SMatrix{4,4,Float32}), but since Float64 is supported as an element type for GLAbstraction, my automatic conversion code doesn't convert it to Mat4f0 anymore.
