If another window is currently in front of us and is fully opaque,
we can just skip to the next window. This avoids a whole lot of painting
with overlapping windows. :^)
The icons show up both in the title bars and in the window switcher.
Eventually I'd like to be able to minimize to icon, and maybe even have
myself a taskbar.
Katica is now the default system font, and it looks quite nice. :^)
I'm gonna need to refine the GTextBox movement stuff eventually,
but it works well-enough for basic editing now.
This needs some work on the window ordering and things like that, but it
works quite nicely as a starting point.
The keyboard shortcut is Logo+Tab. :^)
Divide the window into 3x3 hot areas and resize in the direction of the
corner where the resize starts. The middle is a no-op area.
This needs some polish but the basic mechanism is good.
Use this to implement incremental resizing for Terminal so that we only
ever resize to fit a perfect number of rows and columns.
This is very nice. :^)
Wait for them to finish a paint, then send them a new resize event.
The exception is when releasing the mouse button to end the resize.
Then we send a new resize event right away.
Windows now learn when the mouse cursor leaves or enters them.
Use this to implement GWidget::{enter,leave}_event() and use that
to implement the CoolBar button effect. :^)
The algorithm I came up with is O(n^2) but given the small numbers of rects
we're typically working with, it doesn't really matter. May need to revisit
this in the future if we find ourselves with a huge number of rects.
This patch also adds a Format concept to GraphicsBitmap. For now there are
only two formats: RGB32 and RGBA32. Windows with alpha channel have their
backing stores created in the RGBA32 format.
Use this to make Terminal windows semi-transparent for that comfy rice look.
There is one problem here, in that window compositing overdraw incurs
multiple passes of blending of the same pixels. This leads to a mismatch in
opacity which is obviously not good. I will work on this in a later patch.
The alpha blending is currently straight C++. It should be relatively easy
to optimize this using SSE instructions.
For now I'm just happy with the cute effect. :^)
This is obviously not always the right thing to do, but it removes some
confusion while using other resolutions. Eventually we're gonna need some
kind of compressed image decoder.
