@MacSlow, if you have time to review or test it? For testing you will need:
I prefer to not enable mouse support by default, as it's a bit experimental. The main differences with your implementations:

Keep in mind that we'd probably want this enabled in Fedora since there would be no other way to have mouse support. |

In gltex_draw(), add gl_x1, gl_x2, gl_y1, gl_y2, to store vertex coordinate. This is cosmetic and should have no impacts. Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com>

Start support for standard mouse, using relative EV_REL events Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com>
input_pointer needs to know the screen size in pixel, and make the pointer stay within the screen boundaries. Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com>
Touchpad and mouse in VM, use absolute coordinate, with EV_ABS. Touchpad is a bit special because it's smaller than the screen, so you need to slide multiple time to go from one edge to the other. Handle double tap and triple tap as paste, to make it easy to copy/ paste with a touchpad. This is very basic, and doesn't include all the quirks from libinput, but I hope it works in most cases. Touchscreen may work, but I don't feel it's needed to support it in kmscon, as you will need gesture/onscreen keyboard to make it useful.

Mouse support is still experimental, so it's disabled by default. Also update the man page accordingly
As the mouse pointer is not really transparent, it's better to hide it when it's not in use.
Select a word by double left click on it. It requires libtsm >= 4.3.0 to call tsm_screen_selection_word() Only handle double click for mouse left button as a first implementation Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com>
Handle the case where the screen is not used, and its width and height are set to 0. Suggested-by: Geo Carncross <geocar@gmail.com> Signed-off-by: Jocelyn Falempe <jfalempe@redhat.com>
