GraphUI GraphShape: createGLRegion() -> updateGLRegion(), called by addShapeToRegion() impl to utilize OutlineShape -> GLRegion ctor w/ proper buffer-size

This way we avoid unnecessary buffer growth and allow creation of 'always' fitting buffer sizes.

+++

Update or freshly create the GLRegion, while allocating its buffers with given initial `vertexCount` and `indexCount`.

Method shall be invoked by the addShapeToRegion(GLProfile, GL2ES2) implementation before actually adding the OutlineShape to the GLRegion.

addShapeToRegion(GLProfile, GL2ES2) is capable to determine initial `vertexCount` and `indexCount` buffer sizes,
as it composes the OutlineShapes to be added.

updateGLRegion(GLProfile, GL2ES2, TextureSequence, OutlineShape) maybe used for convenience.

In case GLRegion is `null`, a new instance is being created.

In case the GLRegion already exists, it will be either cleared if the GL2ES2 `gl` instance is not `null`
or earmarked for deletion at a later time and a new instance is being created.
