Avoid text reflow while scrolling (do not remove minimap area)

[Mekk]

Sublimity works nicely (thank you!) and I already like it, but there is one usability problem:

• I open some file which has (some) lines long so they end „nearby right window border” (in case sublimity is inactive) or slightly overflow (when it is active)
• with minimap shown, those lines overflow
• I start scrolling,
• minimap is hidden and all those lines are reflown (no more overlap), what causes buffer to be repositioned
• I stop scrolling
• minimap is shown and those lines are reflown again, what causes text to go down quite a bit

It happens even when „problematic” lines are not visible at all (but are above currently displayed part).

Could it be avoided? It would suffice if minimap did not return it's area to buffer while scrolling (it can keep showing old content, or show some empty background with specific color to signal „in progress state”, or just stay empty - does not matter, as long as it keeps those pixels inavailable to buffer)
