Load fallback in order to obtain its index (this is called from in hot-path so we avoid extraneous parameters to minimize impact on code size)

For user-facing functions: return NULL on invalid ID. Important: return pointer is valid until next call to AddRect(), e.g. FindGlyph(), CalcTextSize(

Optimized for batch edits (with same value of 'selected')

Convert RGBA32 to BGRA32 (because RGBA32 is not well supported by DX9 devices)

Helper for ColorPicker4()

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.

This is already called while stepping. The ONLY reason you may want to call this is if you passed INT_MAX to ImGuiListClipper::Begin() because you cou

This is used by ImGui::PushFont()/PopFont(). It works because we never use _TextureIdStack[] elsewhere than in PushTexture()/PopTexture().

API click: on mouse down, move the cursor to the clicked location, and reset the selection

discard the oldest entry in the undo list

find the x/y location of a character, and remember info about the previous row in case we get a move-up event (for page up, we'll have to rescan)
