Add a simple cache to `DocView:get_h_scrollable_size`
This function gets called at every `core.step`, so we should avoid
having to recalculate the scrollable size every time, as it could get
very expensive on long lines.

Francesco Abbate 3b040aabc7 Implement unicode character replacements
Useful to draw whitespaces with alternate characters and colors
without slowing down the text rendering.

A new API is implemented. A renderer.replacements object can be created
to list the replacements.

In turns the function renderer.draw_text and draw_text_subpixel now accept
two optional arguments for replacements.

Francesco Abbate 3426bc5d73 Introduce subpixel text positioning within rencache
In order to fix the issue with cursor positioning a subpixel-aware draw
text operation within rencache was required.

With this modification the cursor positioning problem is completely
resolved.

A new function renderer.draw_text_subpixel is introduced to perform
consecutive, inline, text drawings with subpixel accuracy.

Francesco Abbate 9ff6a0325e Mostly fix problem of offset with cursor positioning when using mouse
In order to get right the cursor position on text on mouse clicks it is
needed to take into account text's subpixel positioning.

This fix mostly corrects the problem but cursor positioning is still
somewhat inaccurate for long lines due to repeated commands to draw a text
along a line. Repeated draw text calls make the subpixel information
lost and small errors will add-up.

Francesco Abbate 3b30bfa18b Improve left/right scrolling behavior for DocView
With the new behavior when moving right and triggering a scroll in the
right direction a subsequent movement left do not longer triggers a
scrolling to the left.
The scrolling to the left happens only when needed for the visibility of
the current position.

In other terms with the old behavior the scrolling was purely a function
of the position and was adjusted even when not strictly needed for the
visibility of the cursor.
Now the scrolling is no longer a pure function of the position but it
has a "memory" behavior. The scrolling will be adjusted only if needed
to accommodate the position of the cursor.

Reduce also the width of the margin when the scrolling will be
triggered and calculate as a function of the font character width.

With the modification now Lite behaves like the other editors. In
addition the selection of text with the mouse is much more easy when
a scrolling of the line is needed.
