Single quads are drawn as a TRIANGLE_FAN, with 4 verts in the same order.
Multiple quads now use PRIM_QUADS_XXX and will need further work. Only 8 places still use this.
Part of T49043
Each function takes a bool (filled vs outline) and a color. We already had multiple ways of passing color in; these are still here. Special variant for anti-aliasing.
- took GLenum out of interface
- removed UI_RB_ALPHA flag (only one place really used it)
- use exact vertex count
- removed redundant state changes (BLEND, LINE_SMOOTH)
See intern/gawain for the API change. Other files are updated to use the new name. Also updated every call site to the recommended style:
unsigned int foo = VertexFormat_add_attrib(format, "foo", COMP_ ... )
Take advantage of 2D functions, rotation about the X Y or Z axis, uniform scale factors.
We no longer need to call gpuMatrixBegin_legacy() before using the new API locally in functions.

NOTE: This is really a backend-only implementation, nothing is changed in the UI
Adds a tab button-type and the basic drawing and handling code for it.
More work needs to be done on it, but idea is to get in ready for usage in the
topbar.

Replaced all calls to `imm_draw_line` by plain `immVertex2f` calls, and
removed `imm_draw_line`, as that function was not supposed to exist in
the first place, and causes unnecessary calls to `immBegin`/`immEnd`.
Part of T49043
ui_draw_but_TRACKPREVIEW
Changed stipple shader usage to a bunch of GL_LINES with flat color
OpenGL immediate mode: interface_draw.c (end)
Eradicate leftover legacy functions.
Fix a crash with histogram resolution.
coding style, float literals
Converted some (expr / literal) to (expr * literal) where it does not impact readability.
Simplified a few function calls.
ui_draw_but_COLORBAND
Introduced a new checker shader to be used mostly on transparent areas.
OpenGL immediate mode: interface_draw.c (cont)
ui_draw_but_UNITVEC
Introduced a new shader to be used for simple lighting.
all is in the title too..

I change UI_draw_roundbox_gl_mode to use immediate API.
The rest of the change is the call to the function.
I also make some change in UI_ThemeColor4(int colorid) for eg to make convenience to use.
I would really like to know if it's the good way to do, if yes I will make all the change in the node_daw.c after, else say me what's wrong and how to deal with color else.

Was already done for immediate mode, but rearranged code to make a clean separation. Cleaned up #includes for code that uses this feature.
Added same for batched rendering.
This serves as a good example of the Gawain API. (I’ve thought of a
better way to draw drop shadows, but that can wait!)

This is what I had in mind for D1753.
This diff adds a 6th drawing mode to the Waveform Scope.
The new mode shows the RGB colour channels overlaid as a "Full colour" waveform.
The old "Red Green Blue" mode is renamed "Parade" which is the standard industry
term for RGB channels shown side-by-side.
This full colour style of waveform is very much more useful for colour grading than the
Parade mode and is the default waveform for many artists.
Files from older Blender versions which show scopes open as expected.

The purpose of the patch is to replace deprecated glShadeModel.
To decrease glShadeModel calls I've set GL_SMOOTH by default

Each LINES draw call is now responsible for its own line width. No need
to set it back to its 1.0 default after every draw.
This eliminates half our calls to glLineWidth , similar to last week’s
work on glPointSize.
I put all usage of GL_POINTS under the microscope. Fixed problems &
optimized a couple of spots.
- reduce calls to glPointSize by about 50%
- draw selected & unselected vertices together for UV editor & EditMesh
- draw initial gpencil stroke point the proper size
- a few other smaller fixes
New policy: each GL_POINTS draw call needs to set its desired point
size. This eliminates half our calls to glPointSize (setting it back to
its 1.0 default after every draw).
The is intended to replace the deprecated glPolygonStipple() calls with a shader
based alternative, once we switch over to GLSL shaders.
