The scanline orders “bottom_top” and “top_bottom” contain an underscore.
Therefore, the underscore is no longer an appropriate separator for the
test texture filename parts (TGA type, color format, scanline order).
The scanline order ”bottom-top” has been changed to ”bottom_top”.
The scanline order “top-bottom” has been changed to “top_bottom”.
The scanline order names were changed so that API consumers can check if
“tga_encoder.features.scanline_order.top_bottom” is truthy instead of
having to check “tga_encoder.features.scanline_order["top-bottom"]”.
This is a breaking change, but since no release of tga_encoder happened
since commit 01bcbbf927 which allowed the
scanline order to be specified, it can not affect any mod on ContentDB.
If the features table uses keys with truthy values, it is easy to check
for the presence of some feature by checking if the corresponding table
entry (e.g. “tga_encoder.features.color_format.A1R5G5B5”) is truthy.
