Problem: Endless loop when gui_mch_stop_blink() is called while blink_state
is BLINK_OFF. (zdohnal)
Solution: Avoid calling gui_update_cursor() recursively.
Problem: Slow redrawing with DirectX.
Solution: Avoid calling gui_mch_flush() unnecessarily, especially when
updating the cursor. (Ken Takata, closes#2560)
Problem: Duplicated code for getting a typed character. CursorHold is
called too often in the GUI. (lilydjwg)
Solution: Refactor code to move code up from mch_inchar(). Don't fire
CursorHold if feedkeys() was used. (closes#2451)
Problem: balloon_show() only works in terminal when compiled with the GUI.
Solution: Add FEAT_BEVAL_GUI and refactor to move common code out of the GUI
specific file.
Problem: Cannot use 'balloonexpr' in a terminal.
Solution: Add 'balloonevalterm' and add code to handle mouse movements in a
terminal. Initial implementation for Unix with GUI.
Problem: GUI window always resizes when adding/removing a scrollbar,
toolbar, etc.
Solution: Add the 'k' flag in 'guioptions' to keep the GUI window size and
change the number of lines/columns instead. (Ychin, closes#703)
Problem: Mac features are confusing.
Solution: Make feature names more consistent, add "osxdarwin". Rename
feature flags, cleanup Mac code. (Kazunobu Kuriyama, closes#2178)
Problem: MS-Windows: composing characters are not shown properly.
Solution: Pass base character and composing characters to the renderer at
once. (Ken Takata, closes#2206)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: After aborting an Ex command g< does not work. (Marcin
Szamotulski)
Solution: Postpone clearing scrollback messages to until the command line
has been entered. Also fix that the screen isn't redrawn if after
g< the command line is cancelled.
Problem: When the GUI window is resized Vim does not always take over the
new size. (Luchr)
Solution: Reset new_p_guifont in gui_resize_shell(). Call
gui_may_resize_shell() in the main loop.
Problem: Warning for assigning negative value to unsigned. (Danek Duvall)
Solution: Make cterm_normal_fg_gui_color and _bg_ guicolor_T, cast to long_u
only when an unsigned is needed.
Problem: In the GUI the cursor is hidden when redrawing any window,
causing flicker.
Solution: Only undraw the cursor when updating the window it's in.
Problem: On MS-Windows large files (> 2Gbyte) cause problems.
Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct
stat". Use 64 bit system functions if available. (Ken Takata)
Problem: When using feedkeys() in a timer the inserted characters are not
used right away.
Solution: Break the wait loop when characters have been added to typebuf.
use this for testing CursorHoldI.
Problem: The versplit feature makes the code uneccessary complicated.
Solution: Remove FEAT_VERTSPLIT, always support vertical splits when
FEAT_WINDOWS is defined.
