[Gimp-gui] Prioritize loading speed, dismiss fonts loading.

[Fulvio Massimo Mariani <fulviomassimomariani gmail com>]

Hello. 

I invite developers to take in consideration the question of gimps launching speed. I think this is the very first issue to solve, before many other things. 

It can take up to 1.30 mins to load the app, and this is an unreal time for 2018 standards because of fonts loading.

I suggest to dismiss completely the fonts load/preload during gimps launch.

In 90% of case gimp is used for photo editing, crop, quick edits, not for adding texts to the images, via the text tool. In 90% of cases gimp is opened and closed without hitting once the text tool.

Also consider that a designer usually has more than 3000 fonts installed, and waiting gimp to load em all, is quite a waste of time if they wont be used. Gimp is mostly a photo editing software, not a paging software.

Gimp should be ready to work in 5-6 seconds from the exe launch, i really think this is the key.

Light apps are the key for the future.

Postpone font loading in a second moment (delayed background loading), or use a selective loading process, once the text tool is selected.

Best regards. 

Fulvio

Stopping to add/subtract the appropriate angle to make various tools and
filters match the angle measured by the Measure Tool is a bit of an
interruption.

Is there an option somewhere (that I haven't found - I looked in the
toolbox and in Preferences) to tell the Measure Tool to show angles from
0 to 360 counterclockwise to match the angles shown by the Paint Tools?

And a second option to tell the Measure Tool to show angles from 0 to
+/- 180 degrees to match the layer arbitrary rotation operation?

And a third option to tell the Measure Tool to show angles from 0 to 360
degrees *clockwise*, to match Filters that measure angles clockwise
instead of counterclockwise from the positive x-axis? And etc if there
are other starting points/directions for other Filters/operations that
take angles as user input?

If there aren't already such options available, maybe it would be a good
idea to have all angle measurements for all tools and filters be
counterclockwise from zero at the positive x-axis? Though some angle
measurements are more comfortably done starting from 0 degrees at the
positive y axis.

Here are various ways current GIMP tools and operations measure angles:

* The "click/shift to position and paint" angle measurements measure
counterclockwise from zero to 360 degrees, with zero being at the
positive x-axis.

* Filters/Blur/Circular Motion Blur and Linear Motion Blur angle of blur
both run from 0 to 360, counterclockwise (matches the Paint tools).

* The "View/Rotate View/Other Rotation Angle" angle of rotation
measurements from 0 to 360, but *clockwise* (opposite direction from the
Paint tools) from the positive x-axis.

* For arbitrary rotation of a layer, the rotation measurements from
always from 0 at the positive y-axis, running from -180
(counterclockwise) degrees to +180 (clockwise) degrees.

* The "Measure Tool" measures the angle from the closest of the positive
and negative x axes. So the maximum angle the Measure Tool will show is
90 degrees, which means there are four angles (one per quadrant) that
measure 1 degree, four angles that measure 2 degrees, four that measure
3 degrees, and so on, all the way from "just over 0" to "just under 90
degrees", with 0 and 90 degrees only being measured at two angles each,
being the positive and negative x and y axes, respectively.

Rotating a layer or selection to match an angle measured by the Measure
Tool requires some fairly complicated adding/subtracting. Let's say you
measured an angle of 27 degrees in the third quadrant. So starting from
0 rotation, add 90 degrees to get to the negative x-axis, and then add
27 more degrees, so rotate the layer or selection by 90+27=117 degrees.

Painting a straight line at a given angle that was measured using the
Measure Tool requires adding/subtracting 0 or 90 or 180 or 270 degrees,
depending on the direction of the painted line vs the angle measured by
the Measure Tool.

And etc.

Here are some possibly relevant bug reports:
