Francesco Abbate c97fa9a3a6 Fix bug with wrong hashing of rencache commands
The command in rencache.c (Command struct + variable length text) was
incorrectly sized. As a result some bites at the end of the command payload
were uninitialized and was causing hash to randomly change forcing the
system to redraw many more areas.

Since the text of the command for DRAW_TEXT commands is written beginning
at the offset of the text field we compute the bare size of the command as
offsetof(Command, text) instead of sizeof(Command).

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 b33167ca4b Revert "Remove unused data field in RenFont"
This reverts commit 461266e97d.

Related to github issue #122.

The void *data field is not used but the glyphset index can
someting be equal to -1 and the unused field prevent faulty
writes before the allocated struct.

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 35f31c8fbc Fix font rendering artifacts bug
Seen with some fonts like FiraSans, github issue:

https://github.com/franko/lite-xl/issues/46

The fix works essentially by looking to the bounds of each glyph to
accurately ensure that there are no overlaps between the glyphs.

The construction of the font atlas was changed to make some related
improvements now that the bounds of each glyph are know. The main
changes are:

- no longer align glyph on the baseline but align them on their upper
  bounds. We ensure this way that very tall fonts do not leak in the
  upper part
- terminate the row based on x bounds of the glyph to be more accurate
- for each row keep trace of the y of the more larger along y of the
  glyph. The value is used to start a new row to be sure that the new
  now does not overlap with the previous one
- sort glyphs by y size before drawing them. In this way the space
  utilization is better. The algorithm used is the very simple insert
  sort. It behaves like O(n^2) with the number of characters but should
  be ok since n is always small, typically below 128.
- compute the optimal image width and height for the given font's atlas
  for optimal memory usage. As a bonus now the lite's code don't have to
  try and repeat to get a good image size
