Variations on the previous patch: instead of choosing the number of columns based on font size, these patches will use a fixed number of columns regardless of fonts size, depending only on whether the screen orientation is portrait or landscape.
1P/1L = single column in either orientation.
1P/2L = 1 column portrait, 2 columns landscape
2P/3L = 2 columns portrait, 3 columns landscape
I haven't tested these, maybe someone with a Forma or other landscape-enabled device could try them out. Paste the patch for your device into librmdsk.so.1.0.0.yaml, and test on an ePub book that doesn't have an embedded XPGT stylesheet.
