85f84dd383 Documentation and cleanups to the RotSprite methods. 2013-09-18 02:37:13 +02:00

80ca05e448 Simplified Rotsprite algorithm. 
It is used to perform any kind of rotation with the RS imagepath
function which could only rotate in multiplies of 90 degrees previously.

bbb6631f79 Functions to rotate an image 90- or 180- degrees. 
(Still need an Image Path Function to make these accessible from WML.)

b5240e1bf9 Rewrite the blending algorithm. 
The rewrite only has minor visual differences, ImageMagick's

`composite -compose difference'

shows no visual differences.

The change makes it possible to optimise the code on the ARM Cortex A8
using NEON instructions.

63528912fa Fixes crash when using fullscreen on Mac OS. 
Fixes a problem when using the SDL nightly builds (post 1.2.14).

The direct blurring of the screen fails on OS X, since the surface is
not a neutral surface, so only testing for 32 bpp isn't enough. Exports
the neutral surface test from sdl_utils to have a proper test in the
canvas code.

This commit helps fixing bug #18319, but the speed of rendering is still
too slow.

Thanks to Alarantalara for testing the code on OS X.

7ca44f7ac6 Big optimization of terrain rendering by removing all empty images. 
This make screen update (zooming, ToD changes, etc) several times
faster, gain some fps (esp. for complex map), optimize some animated
terrains (stop refreshing empty parts) and spare some memory
(sometimes, not clear yet)

Also remove the noise in :layers.

Note: This is an improved version of 2010-10-06T16:07:43Z!alinkmaze@gmail.com from the OGL branch

dd185c0174 New imagepath function ~L(lightmap.png) to do ToD color-shift per pixel. 
Possibly temporary, since added for the prototype of local ToD light
transitions.  But I suppose it could be used for some special effect
on units.
