Glass pane "edge" texture is rendered as cutout rather than solid

With 26.1’s changes, due to the presence of transparent pixels in the texture file, the “rim” of glass panes (top, bottom, and connected edges) will render using the “cutout” method rather than “solid”. This may cause negative performance impacts.

Ideally this should be rendered as “solid” instead. This could be instituted in several ways:

• introduce a .mcmeta parameter that forces a texture to render as solid rather than cutout, like the existing transparent parameter

• allow for render layer to be specified in the model file using the texture

• modify the texture to fill in all transparent pixels (this is a poor and non-recommended solution as it would affect particles and also break the convention that unused areas of pixels be transparent)
