CEGUI General

• Texture filtering should use trilinear filtering, instead of bilinear for magnification in some (!) cases. Need to figure out which cases need which and implement a switch, etc
• Replacing ColourRect with Colour would allow us to strip all per-vertex attributes for colours and allows us to use a highly performant uniform instead. People who want fancy fonts etc should just use Bitmap Fonts and Widgets can simply be changed to using different Images instead of applying Gradients with ColourRect there as well.
• setAlpha apparently triggers recreation of GeometryBuffer should be replaced by a uniform instead of applying it to the per-vertex attributes (Done by Henri - Todo:Check if this is really 100% bullet-proof)
• Check for the necessity and performance loss of unproject calls : d_owner->getRenderTarget().unprojectPoint(*d_geometry, in, p_out);

Opengl Renderers

• Improve OpenGL Renderer(s) extra states functions (and also rename it):
  • Add and also do the restore for: glUseProgram(0); glBindVertexArray(0); glBindBuffer(GL_ARRAY_BUFFER, 0); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER,0);
    see https://github.com/kortemik/RBDOOM-3-BFG/blob/cegui/neo/sys/sdl/sdl_glimp.cpp#L553

  • What about blending and scissor test?

Renderers

• If applying the ColourRect changes is successful, then it should be possible to use instancing for the vbo's which basically allows to use instancing of a vbo fto render the entire CEGUI UI

SVG

• Need to implement MSAA in all Renderers as alternative for the alpha blending AA
• Need to fix D3D11 Rendering of SVG demo

SampleBrowser

• Separate duties (input, Renderer-related stuff, etc) in different managers. Reduce the inheritation levels to a maximum of one. Simplify the classes. Make initialisation and deinitialisation more overlookable. Remove namespace "CEGUI" from all Sample-related stuff.

CEGUI docu

• Improve cegui docu:

[17:07:59]	Ident	we really need to fix the docu for how to set up an application for CEGUI
[17:08:33]	Ident	and by "we" i mean someone except me
[17:12:50]	timotei	Ident: Well, there is already one, isn't it? :P
[17:13:07]	Ident	it lacks crucial info
[17:13:12]	timotei	Like?
[17:13:19]	Ident	how to deinitialise cegui
[17:13:25]	Ident	how to update cegui exactly (code samples)
[17:13:37]	Ident	for example the notifydisplaysizechanged
[17:13:49]	Ident	or how to render in detail
[17:14:11]	Ident	there were some posts in the forum in that regard too
[17:14:20]	Ident	when i have time i look through all of them and update the api docu
[17:14:21]	timotei	CEGUI_SamplesBrowser provides some examples as far as I know
[17:14:24]	Ident	nah
[17:14:31]	Ident	thats not a good place to look for this
[17:14:32]	timotei	Or you mean, simple CEGUI-ed application?
[17:14:35]	Ident	the rendering is super-specific
[17:14:43]	Ident	and also some of it is hidden
[17:14:55]	Ident	it doesnt make sense to look into SamplesBrowser
[17:15:13]	Ident	thats not what the browser is there for
[17:17:35]	Ident	how to make an application using cegui should be well documented with examples in the api docu
[17:17:43]	Ident	this should be the only resource for this
[17:17:57]	timotei	I see :)
[17:17:59]	Ident	then- how to initialise resources, load layouts and use cegui - this is where the samples come into play
[17:18:00]	Ident	because
[17:18:12]	Ident	there is many different ways to set up a cegui application
[17:18:21]	Ident	we cant cover all
[17:18:39]	Ident	of course we can and should provide code snippetsd

SVG Tessellator tests

Create em', it is easy according to mpreisler

[15:05:35]	mpreisler	just copy a .cpp file and fill it with your tests

Add tooltips to some demo

It is currently not covered anywhere. Or is it( need to check!)?
