Description Sven Gothel 2023-09-30 01:09:43 CEST

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.
