Godot: Touchscreen buttons shapes are not centered respect to the texture

[MaurizioMacri]

Godot version: 3.2.1

OS/device including version: Windows 10

Issue description: Touchscreen buttons shapes are not centered respect to their texture even if the option "Shape centered" is checked. It seems that the shape is shifted on the right bottom side of the texture.

Steps to reproduce:

• Add a touchscreen button node to the scene
• Add "normal" and "pressed" textures to it
• Check the option "Shape centered"
• Add a circle shape with a radius that makes the shape bigger then the texture
• Run the scene and tap/click on the extreme left side of the texture

Minimal reproduction project:

Could confirm with the attached MRP.

The problem comes because the (correct) transform used for drawing:

Is not the same one as the one used when checking if the point is inside the shape:

Specifically, notice the lack of texture->get_size() in the second snippet.
